when surveyed, 55% of mean mama readers not too shy, confused, or bored to participate responded that twitter is, indeed, "silly."
jo myles pointed out a flaw in my poll when she noted that there should be a "silly, but I still like it for some reason" option. i agree, since that's my basic take on twitter. although i recommend that those with a serious interest in the subject (i.e. beyond "silly or not?") read what alex steed has to say about it.
personally, i "unfollowed" a few people who i was finding unaccountably irritating and started following some friendly new people, and i feel much better about the whole thing.
