I try a ton of different services aka Web 2.0 applications, most of them get used for a day or two and then dropped.  However, every once in a while I come across one that actually makes it into my regular rotation and I start recommending it to people.  One of my favorite applications that I use all the time is Jott.  If you've never heard of it, you need to get acquainted.  It enables consumers with cell phones to leverage voice recognition at a personal level, and it's very cool.

At its core, Jott is a voice recognition and message-sending system.  You dial the Jott 800 number and it recognizes you from your caller ID.  You then tell it who you want to send a message to ("Myself") and then speak whatever message you want sent to that person "Don't forget to wake up early tomorrow, some *#@!*$&^ scheduled a meeting for 8 am tomorrow."  Jott will then automatically transcribe that text for you and send it to the person you wanted to send it to.  And the voice recognition is very good.  This is very powerful enterprise-grade technology that they've made accessible to the average person, which is way cool.

Most of the time I use it to send emails to myself, but there are a ton of other potential uses for it as well.  Some of the fun things I do with it:

• Send Twitter messages from my phone
• Hook it up to my Sandy account so I can feed Sandy from my phone (Sandy is a virtual secretary service that reminds me of todos and appointments)  (Mmm... lots of Web 2.0 goodness there, no?)
• Spew ideas into it while I'm driving which I then archive in Gmail for further reference.  This thing is worth its weight in gold to me just for this purpose, I used to lose a lot of good idea because I didn't have a pen and paper handy.

One of the very cool technical things they've done with it is set up a way to connect the output of a Jott message to another system using an HTTP post.  So what they've essentially done is provide a voice recognition system that you can use to feed other applications.  That's a huge barrier to entry that they just took down in one fell swoop.  It's really fun to use in development because all of a sudden you have a totally new way to interact with the user.  I've already cooked up some really cool little apps using it, maybe some day I'll put them up publicly.

I love Jott and I use it all the time, but I don't think I've ever mentioned them before.  Just wanted to send some props to them.
