I often find web pages that I would like to know when changes. This can be anything from a blog posting a new article to a sales page offering a new item. I have never been 100% happy with the many different form of subscriptions offered. Some pages offer e-mail subscriptions other only RSS feeds.
A while back I came across www.changedetection.com/ it is a very simple service that solve this problem in a neat way. It will check a web page for you either daily, weekly or monthly. If there has been any changes to the page since last time it will alert you. You can have it alert you only if something has been removed or if the new content contains a special word. It has a self explanatory interface.
For instance you could have it to track https://twitter.com/Warigeiko and tell it to check it weekly. That way you would get a weekly digest of my tweets. The address you give it can contain parameters like this search for chawan on trocadero. The possibilities are endless. Some of the things I have used it for:
- Has potter X added new items for sale on their web page today?
- Are there any new kittens for sale from this breeder?
- Let me know when this blog is updated
