I recently started texting with a webcomics buddy. We'd been exchanging emails, but we both have tiny humans at home and they ended up being very sporadic. The texts have been delightful and a wonderful workaround. We can chatter at each other at odd hours, but like email, the other responds when they have time. It feels very freeing compared to IM or emails, because phones just sort of follow you everywhere and the nature of the beast lends itself to short bursts of conversation, rather than a long committed one. I've only ever texted people who are local and having a long distance text pal gives an interesting sense of proximity. I don't think I'd want a dozen texts pals, but this has been pretty neat.
