My house and bandmate has a problem. Oftentimes, when I send him interesting links that happen to have long URLs, for some reason his Hotmail account splits up the link, ending the part it sends to the browser at some arbitrary point (I think the point has to do with where Mail.app was displaying a line break when I sent the email).
Recently I found a solution to this problem: TinyUrl.com. They take your long, crappy URLs and parse them into something simple, like “http://tinturl.com/6”. That kind of thing won’t cause a line break. Hotmail won’t freak out. They’ve got a bunch of other smart uses for the thing on their homepage, but I liked this one because it solved a problem I’d encountered that I never thought would be solved.
