How many times you have felt like that? How many times you wanted to know if that damn thing is only happened to you? if it was just a web site fail to load you would use downforeveryoneorjustme.com . But if it is about something else, err… something about Firefox or a GNU/Linux problem or just any random thing? There’s something better you can use.
The Twitterverse. Lot’s of people share their experiences there and isn’t it great if you can check Twitterverse for that random thing. But how? summize.com [search.twitter.com now] which is now acquired by Twitter itself does search the Twitterverse real time & give you the answers. I’ve already used it few times & succeeded :D . As an example I checked whether Twitter RSS feed is down, using summize ;)
