In the last two days I have discovered more cool web sites than I have in the previous six months. If you haven’t already stumbled upon it, stumble upon is a great way to discover new sites. I am a regular net user, and I spend a lot of time trawling the web, but it’s easy to get bogged down in habit and routine. Stumble Upon breaks the habit, and throws you out into the universe to discover sites that fit with your specified interests. User rankings also strengthen the system. Of course you also get sent to some sites that are less than amazing, but with a few hours of stumbling, you’ll have enough interesting sites bookmarked to spend the next month looking at. Truly inspiring stuff.
