PageReboot does one thing and it works. Enter any URL and a rate of refresh, and the site will display that page, then refresh automatically on your set schedule. There is also a bookmarklet option so you can drag links to start refreshing. It's a nice resource. Some uses might include:
- eBay listings, making sure you get the last bid.
- Blog comments, keep track of comments instantly so you don't miss an opportunity to respond (think reputation management.)
- Twitter, keep track of incoming tweets, responses to your tweets and direct messages.
- Forum postings, forums update rapidly and you can keep tabs on things so nothing gets out of hand (also reputation management.)
