Yahoo Pipes mashup SnackUpon takes the ideas behind two popular web applications—Delicious and StumbleUpon—and creates a customised RSS feed that delivers content you might like based on your Delicious bookmarks. The idea is brilliant: You already subscribe to sites with your newsreader because they deliver content that you like, but you don't have much control over what content the publisher of that site covers. With SnackUpon, it's like you've created a blog that publishes content based solely on your likes. Granted, that assumes the SnackUpon works as advertised, but after testing it out on my Delicious account, this is one feed I'm planning to keep in my newsreader. If you plug in your Delicious ID, let's hear how well SnackUpon matches your taste in the comments.

Facebook has added a feature which lets you populate your Facebook page with your data from Flickr, Delicious, Picasa and Yelp - without needing an extra application to do it.

To import activity from other sites into your Mini-Feed (and into your friends' News Feeds), hit the  Import button on the top left of your Mini-Feed. You'll get the option to chose which service to import from (see photo above).

The tool also lets you get information from Yelp - and Digg integration is on the way too.

Schedule free wake-up calls and reminders online with web site Wakerupper. Just enter the time and date you want your call, your timezone, phone number, email address, and an optional bit of reminder text that will be played text-to-speech style when you get the call. The site requires no registration, though registration is possible if you want to use the service for more than the occasional one-off wake-up call. Most of us have learned to use our cell phones as anywhere alarms, but if you're paranoid about waking up when you're travelling or before an important meeting, Wakerupper is a useful tool for creating anywhere, anytime wake-up calls (a little redundancy is always calming).

Useful if you're going abroad and need to speak to the locals.
