I've written before about Web 2.0 apps that suck. Twitter is one that comes to mind. It's a popular web app, but for no good reason. Fortunately they'll eventually disappear once they run out of venture capital money. Like so many web-based companies, they'll never make a profit. It's rare to find a Web 2.0 app that offers a useful service. So it's sad for me when I do find one and I know that like Twitter, it will eventually run out of money and then I won't be able to use their service.
The app in question is
Jott. Jott is the first useful voice recognition application I've seen. Here's the gist of how it works:
After registering a free account on Jott, you dial up a 1-800 number on your cell phone. Jott asks you what you want to do. You speak a phrase to Jott, such as "Calendar". It then asks you what the appointment name is, and what time you want to be reminded. Then it adds it to your Google Calendar. You can also do this with text messages, but why would you?
There are plenty of plugins for the free service too. You can add other services, such as Twitter or Don't Forget the Milk. They even have an SDK (of sorts) to create your own plugins.
I don't see how this company will ever turn a profit. Hopefully someone with some deep pockets will buy them out. Imagine if Microsoft bought this for Exchange. You wouldn't need to log in to a computer to setup a new appointment or to-do item. You could just pick up your phone, any phone... not just a smartphone or a blackberry, and setup that meeting or task item. As a standalone product I don't believe it can survive. But as part of a larger product, I think it would be profitable.
In the meantime, check out Jott. I've only been using it for two days so far and I've already found it valuable.
