Back in November I stumbled upon stumbleupon. This is another great web2.0 company that crosses search with social networking.
I love the site, it's made me fall in love with the web in a new way. I love the randomness, the unexpected stuff it throws up that I'd never see otherwise.
So how does it work?
Download a toolbar that sits in your browser, and any time you fancy you hit the stumble button and you'll be taken to a new webpage. The pages you are shown depend on the interests you've previously stated (over 500 options), the friends you've made and stumbleupon learns from the likes and dislikes you state with one click as you browse. All pages have been recommended by other stumblers, so it neatly sidesteps all the companies that pay search engines to get on the first few pages, and you tend to get interesting, high-quality sites.
The blogging feature is easy to use; you can add comments to any webpage that are copied to your blog, and even if you don't want to comment on a page you can review everyone else's comments. You can recall the full list of sites you've given the thumbs up or down to. It's also a lot quicker than 'proper' grown-up blogging, so I've tended to switch to that for capturing a lot of the random, little things that catch my eye.
You can browse stumblers by their interests, or see who liked the page you're on, and send stumbles to your friends (this is easily the best social networking feature).
Some of my stumbles are blogged on my stumbleupon homepage. There's the odd gem, but a lot of totally random stuff like oneword, footprints in the sand and weirdly pretty odd too.
