I previously mentioned using Yahoo Pipes to creating custom Twitter groups. Here’s some other things that might be helpful.
- Subscribe to your Twitter feed in Google Reader. This will give you nicely readable archives that don’t suffer from whatever weird Ajax bug the regular Twitter pages have.
- In Yahoo pipes, set up a pipe for the public feed and filter on a keyword like PodCamp, SXSW, VON, etc.
- Subscribe to THAT feed in Google Reader and you have a pulse-monitor of near-realtime discussion from the cutting edge folks about your keyword.
- Share your Twitters in your Google Reader shared feed. Using tags in your shared items, you can specify, for example, Twitterstream.
- Use a filter in Yahoo Pipes on your Google Reader shared feed, filtering the content of the id field for your tag – instantly, you have a shared “best of Twitter” page and feed.
- Use a plugin like Feed Wordpress to auto-blog things in your best of Twitter feed.
What innovative ways can YOU make use of what you do on Twitter?
Updated with bonuses:
- Start by putting your Twitter RSS feed into Feedburner – this will give you a good, clean feed.
- Set up Feedburner’s Pingshot and other services as appropriate, including applying Creative Commons licenses.
- Twitter RSS does NOT hyperlink stuff, so if you want your Twitter posts to have appropriately linked URLs, you’ll need to use a Regex replace filter in Yahoo Pipes prior to publishing the RSS.
- Stuck wanting to blog, but have blogger’s block? Pick a random Twitter and use that as your topic and blog post title.
