One of my gripes about web pages is that too few have RSS feeds. I want to read them when they change, but it's too much of a pain to go back to that page day after day (especially when they only change every week or two).
Well, it's the internet - and somebody has solved that problem for me:
ChangeDetection - Know when any web page changes
You enter a URL, and customize how you want to be notified (email, RSS) and how often to check, and voila! You'll be notified when a change happens.
I've got two pages I'm watching, Bill Maher's New Rules which I find endlessly entertaining, and Obama's executive orders.
