Yes, I’ve returned to Twitterdom. I still don’t have much use for it, personally, but:
A. I’m a geek, and it’s a geek toy. Must. Have.
B. The rest of the world seems to find it useful, including some of the band promotion sites that I use (I’m looking at you, ReverbNation).
So, despite not being able to access Facebook or Twitter from work, and despite my lack of a geekly phone gadget that is useful with said apps (which drops my geek cred back down into the toilet), I’m back in the Twitterverse.
