When you subscribe to a feed, you easily get notified of the latest changes and new content in your favorite news site, blog, etc. What if there is no feed to subscribe? Should you check it every day??
What browser do you use? There are several progams that will monitor web sites and let you know if anything has changed. Web Site Watcher is one, but it isn't free. Webmon, http://www.btinternet.com/~markwell/webmon/, is a free one. I think Check&Get offers a free version as well, http://www.topshareware.com/Check-And-Get-(Freeware-Edition)-download-8595.htm. I think FireFox has a few addons that do this also, Page Update Checker I believe is one. Or as you say, just check every couple of days or so.
Thank you very much for the answer!
