Page2RSS is a service that helps you monitor web sites that do not publish feeds. It will check any web page for updates and deliver them to your favorite RSS aggregator.
Feed is the best way to tack changes to any web page as compare to bookmarks. We explained feeds in details here alongwith video.
Now coming back to page2RSS, just paste URL of any web page, update to which you want to track, and page2RSS will create a feed for it which you can subscribe into your favorite feed-reader like Google Reader.
One more good thing with page2RSS is it cache pages over the time. So if you want to see how entire page looked after particular update, you can click on a link saying “View Entire Page”.
Also for easier subscribing, it gives you a bookmarklet option. About languages, it available in Russian apart from English as of now.
A simple but highly useful service I must say! 🙂
