I was randomly searching for bands on Twitter the other day, when I came across a tweet by @mashable with a link to this farily comprehensive list of artists maintained by Canada’s Gabriel Nijmeh. Some of the more active and engaging musicians on Twitter include @johnroderick (of The Long Winters), @mchammer (who must Tweet 24/7 given the number of updates he makes), and (questo of The Roots). Oh yeah, though I’m not a musician, you can find me on Twitter at @bumpershine (where I Twittered about this spreadsheet a few days ago).
