As far as the little things we do with our boredom go, compared to other timekilers, Formspring is just a kid. It hasn't been around that long. Not that Formspring or it's rapidly-growing userbase care all that much.
Not too long ago Formspring was just people trading questions for answers, with a little Facebook/Twitter connectivity mixed in. Once it caught on, the site became more streamlined for use, and mobile friendly.
The latest facelifts extend the connectivity to MySpace and Wordpress, and also now allow you to tradeoff the anonymity of your questions to ask one question to your friends en masse. Nifty stuff here.
Formspring is taking off FAST, and I don't see it going away anytime soon. The more people that hop on and ask questions the more people will take notice. Similar features are already popping up on the social websites we're used to. At this rate it won't be long at all before Formspring changes it's face yet again.
