And here, in alphabetical order to avoid accusations of favouritism, are my micro-biographies of people you should follow:
@andromedababe Observer of shagging frogs, lover of shoosies. Blogs at AndromedaBabe's Blog on teaching and other stuff.
@Crafthole is a archeologist / historian person
@DanielFurrUK is a libertarian Liberal Democrat, who blogs at http://danielfurr.tumblr.com/.
@deborahshelton is an interior designer, see here. She hangs around with the historians.
@doyle2718 - it's me mate from work: Doylie! The only one on twitter, the rest just think I'm odd...
@dr_andy_russell is an atmospheric physicist at Manchester University. Writes a blog. Handy for a knowledgeable opinion on climate change.
@DrEvanHarris is former LibDem MP for Oxford West and Abingdon, and was the party's Science spokesman. He joined twitter recently and immediately gained a massive following of nerds and geeks, he uses twitter like a pro and is responsive to queries. His website is here.
@Drop4three an enigma I have yet to crack, he blogs at dropped
@Duddy an author of several novels of a scientific bent, and Cestrian and Keeper of Snails blog. She has retired from Twitter, but the blog is still well worth visiting
@graemearcher is a statistician and a relatively unpolitical politician who writes an occasional blog post on Conservative Home. He likes swimming, cats and Mr Keith.
@hangbitch always happy with an acerbic comment. She has a blog at Hang Bitch.
@iknowhim I always think of as mysterious, a cause de her avatar. She has a blog, Last Tango in Dulwich. And her twitter background is a very fine, if not sensible, shoe.
@Jackpot73 another friendly soul of the interwebs, who has been sharing my sense of humour, which may or may not be a good idea ;-)
@jme_c is many things including college lecturer at Somerville and MSc Science Communicator at Imperial College, he is suffering geek-envy for my HTC Desire. His website is here.
@KateKatV is @PaoloViscardi's mum! I know this is an impolite way to introduce someone, she also has a blog here.
@laales is a split between Hong Kong and Dorset (which is where I come from), she is a member of the historical faction.
@LadyCrafthole is a photographer who blogs at Lady Crafthole's Blog. She makes little planet photos.
@lahossner is most mysterious, I believe she is a fan of books.
@langtry_girl was best able to finish the sentence: "Understanding the Periodic Table is very much like making love to a beautiful woman..." is an economist, so nearly a scientist ;-)
@localbuilderuk Lover of snowboarding and wine, of which I approve - not so sure about the golf ;-)
@louwiseman joins me from the gardening faction, she seems obsessed with insects at the moment.
@Margit11 was living in Edinburgh but is now living in Munich. Blogs at Intercultural Musings, on being a foreigner in the UK but things will change.
@markgfh science editor of the Times, and fellow science-politics geek.
@MarkReckons is a fellow LibDem, and political blogger - you can find him here. A moderate in all things.
@masticatingmanx is a fan of food, no indication as to how this has affected waist-line but his blog looks pretty healthy. An inhabitant of the Isle of Man, which I have only seen as a distant shadow.
@Morphosaurus a teacher who was able to recognise tunicates from my inept description, keeper of Bastard the Cycad and author of multiple blogs.
@nemski is that rare creature: the American Liberal he comes from just down the road from Malvern (Mrs SomeBeans comes from the UK version). Various sciencey tweets.
@opheliacat a member of the historical faction, she is our woman in New York.
@PatrickBaty and @PapersPaints are one and the same, analyser of historic paints and one-time instructor of tank drivers. He blogs at News from Colourman, he's been on the TV but was upstaged by his cat, Caspar.
@philipmcdermott is a research associate and software engineer. He blogs at http://number23.org/
@Quackwriter author of Kill-Grief and alumni of the Wirral, curator of the Quack Doctor blog, which reports on the wacky medical adverts of the past.
@rebekahthornton is local. She sometimes has a mathematical air about her and is fond of darts.
@ripplestone is from the gardening tendency, although her name makes me think of geology. She blogs at Ripplestone Review.
@robajackson chemistry lecturer, card-carrying red, and trombone player. He blogs on chemistry and politics.
@rose_darling Writer. Editor. Poet. Dreamer. Music lover. Conversationalist. Gastronaut. Traveller. I love it when people write their own biographies! She has a blog here, which I don't think she pimps enough!
@sallybercow I started following all sorts of people for the election. Sally, self described #1950shousewifebot with a familiar surname is by far the most fun
@sarahsiddons seems to come to me from the historical faction, curator of the Weird, Ordinary, Wonderful blog.
@Schroedinger99 is a fellow skeptic, how did I manage not to add him sooner? He has a blog at Bad Reason.
@Sciorama a scientist I know from some time ago, a biological physicist with very red hair.
@Scisu interested in things sciencey, she blogs for BioData.
@smithatcity is a doctor and a Science Communicator in training at Imperial College, she blogs at in bed with medicine.
@Stephen_Curry a fellow scientist, who scatters x-rays from crystals. He blogs at Reciprocal Space.
@stephenemoss a biological scientist, his work was on the BBC website recently. We hang around together at virtual science policy gatherings. He blogs at a little bit at The Mad Professor.
@Steve_P_Knight is the king of lasers. I think we must have met over something sciencey, but I can't remember what!
@TiggerTherese is of the gardening tendency, her bio mentions being an ex-banker - but she doesn't like to talk about it.
@thecredo I think may have escaped from The Thick of It. Originally the owner a mad old bearded-man avatar, this is how I will always see him.
@ThetisMercurio is in her own words rationalist, humanist, satirical... Staunch opponent of Steiner-Waldorf schools, the homoeopathy of education.
