i've set up a 12k_label twitter account to separate my own personal ramblings from label news. i'm not sure if this is better than one account or not. it's more work for me and everyone else... but, it's also more "official".. and those people who only want 12k news can just subscribe to the 12k twitter and not my personal one.
anyway, you can follow it:
"12k", sadly, is taken already... check out twitter.com/12k for a good laugh. i think i see Ralph in there somewhere....
