What Can I Do With Twitter?

I found out about this post because I follow @fuelfrog. I found out about fuelfrog before I found out about @mymm (my mile marker). Not only does My Mile Marker know how to do subtraction (with fuel frog, you need to know the number of miles you drove since you last filled up, with My Mile Marker, you input your odometer readout), but it also makes multiple graphs, predicts how much you'll spend in a year, keeps track of oil changes and the affect it has on your mileage, and just plain works better than fuel frog.

So, add mymilemarker.com to your list, it's a great alternative to fuelfrog. And it can do math.

Also, Twitterfeed is totally different than you describe. You say it's a way to get texts for RSS feeds (there are actual services that do just that, surprisingly), when in fact it's a way to take posts from an RSS feed like @cnnbrk (for CNN Breaking News), @firefox_queries (for the latest support requests for Firefox) or @TheDailyWTF (for computer humor) and create a twitter account other people can follow that's fed by that feed. Most people just use it to have their twitter account updated whenever they create a new blog post.

You even got @timer wrong, you need to first follow timer (it sends direct messages, and you can only receive those from people you follow), and you need to put the number of minutes before the message, not after.

John, I'm not trying to be rude, but it's like you purposefully got everything as wrong as possible when writing this article. Do a little more research next time.
