Twitter is simultaneously a “micro-blogging” platform and IRC 2.0 (as many people have dubbed it), meaning that it sometimes becomes a giant chat channel. Many people (like I do) use what they write on Twitter to enhance their own blogs, or feed it (along with other sources) to services like Friendfeed.
The problem with this is that the ratio between your “original” content and replies to other Twitter users becomes very low, and these so called “@ replies” have little value for people that aren’t in on the conversation.
Continuing my love affair with Yahoo Pipes, I’ve created a really simple pipe that will fetch your non-protected Twitter feed, and filter out all the @ replies. It will also remove the “nickname: ” prefix from the start of each tweet. Just input your twitter username on the form, run the pipe, and choose the “Get as RSS” from under “More options”, inside the “Use this Pipe” section. Feel free to clone it and improve it.
