I was asked recently who (in a Web Development context) is good to follow on Twitter. While this is in no way an exhaustive list, this is who I am following and recommend for good quality or interesting tweets.
In no particular order:
@mattb (Matt Biddulph)
@drewm (Drew McLellan)
@zeldman (Jeffrey Zeldman)
@boagworld (Paul Boag)
@plasticbaguk (Tom Coates)
@gruber (John Gruber)
@simplebits (Dan Cederholm)
@shauninman (Shaun Inman)
@adactio (Jeremy Keith)
I should mention that (apparently unlike most people) I read all the tweets that come in on my stream. This means that I am less likely to be following people who, while very relevant are also a wee bit too verbose (for my tastes – your mileage may vary) on topics that I didn’t follow them for! I’m looking at you, @codepo8 (Christian Heilmann)!
Please comment and let me know who I missed…
