I signed up for a Twitter account a long time ago but I have never really seen much value in it. Perhaps it is because I live in a small town, or maybe it is because I have no social life, but really the micro-blogging aspect just hasn't made much sense to me.
I've tried to find a reason for it in my life. And I even occasionally use it. But until today I hadn't seen an application for it that I saw provided any value - either practical value or purely entertainment wise. However, today I came across the site StrawPoll Now which uses Twitter to broadcast a simple poll everyday and then everyone who wants can participate in it. Sure, the polls can be pretty stupid - but they are still somewhat entertaining and the implementation of the website is pretty slick.
As a technical aside StrawPoll is actually hosted by the same folks who host this website so if I had to guess I would bet the site is built in Ruby. Regardless it's a nice front end and the idea is sort of fun.
