For those of you looking for a free alternative to PowerPoint or Keynote, look no further than 280 Slides. Started by two former Apple employees and backed by Y Combinator, it does an excellent job of mimicking those desktop applications, online. They use Javascript instead of Flash, which makes the whole experience even more impressive. While it won’t solve the problem of having to sit through excruciating Power Point presentations, at least it’s free.

We’ve reported on Last.FM quite a bit here on the Free Line- after all, it lets you stream any music you want to hear for as much you would like. But that is all about to change. Warner Music has pulled the plug on letting Last.FM stream their artist’s music, which will cut down on a large amount of free songs that you can tap your toes to. No more free Neil Young or Death Cab for Cutie. Bad form Warner. That’s not the way to move the freeline.

Of course, some people get their music in less than legal ways, using programs like BitTorrent or BitComet. AT&T has officially come out and said that have never and will never cut down on bandwidth for people using BitTorrent technology. They say that it’s just not a part of their philosophy. They have, however, thought about doing something similar to what Time Warner Cable is doing for it’s internet offering- and that’s charging people per gigabyte of bandwidth.

Of course, if they do charge for bandwidth, this could be a big problem for people using sites like Box.net to store their files. Box.net is an online file storage site that lets you upload any file you want, and also edit documents and photos online. A cool tool, and I hate to see people use it less just because they will get charged more by their internet company for using it. Especially since Box.net is completely free.

And if you’re a Wikipedia addict (and who isn’t?), you should get a kick out of Six Degrees of Wikipedia. It’s a game where you put in two subjects, and see how many clicks it would take to get from one to the other. How far is it to get from Gatorade to Genghis Kahn? Just three. A fun and free way to waste some extra time.
