I’m a fan of FriendFeed. FriendFeed, to me, is total awesomeness. At the time of this writing, I’ve written fifteen posts on FriendFeed (including this one). Robert Scoble loves FriendFeed too. But now, I love FriendFeed even more. Why? Because it’s possible to create truly excellent applications with the FriendFeed API.

The FriendFeed API is far from perfect, but what’s making me love it is NoiseRiver. So, who is behind this masterpiece of an API application? directeur on FriendFeed is responsible for this masterpiece of an API application.

So, what do I like about it? First off, the user interface is excellent. It takes the simplicity of FriendFeed’s user interface and entwines it with an elegance that is so hard to achieve when building a good user interface. Click on the below thumbnail to see the screenshot full-size.

Now, it does more than serve up a pretty user interface. It actually solves some of FriendFeed’s most basic problems. What does it solve?

Well, several people have talked how noisy FriendFeed users can drown out the posts of less-frequent FriendFeed users. Now, if you like the posts of the noisy and quiet FriendFeed users, you’re at a bit of a disadvantage. It’s more difficult to hear the quiet FriendFeed users, and there may be some cases when you’re more interested in what the quiet users have to say.

NoiseRiver to the rescue! It allows you to select which users you like more than others.

Okay, but the noisy FriendFeed users might also talk about topics that you aren’t interested in or don’t like at all. What do you do about that?

No problem. NoiseRiver solves this problem by allowing you to insert keywords and rate those too.

Now, I might really like NoiseRiver, but you are annoyed with something in NoiseRiver’s user interface. What do you do?

Wel, there’s the NoiseRiver FriendFeed room where you can post suggestions, and a lot of the suggestions are acted upon immediately.

In conclusion, NoiseRiver is a top-notch web application that has a great user interface and solves some of FriendFeed’s problems.

UPDATE: Apparently some people think that NoiseRiver actually has a chance of being acquired.
