I’ve been pretty addicted to both Stumbleupon and Del.icio.us in the last few years. Stumbleupon uses a simple thumbs up or thumbs down symbol to rate websites. You click on the “stumble” button and it automatically takes you to a website in that category. If you like it, you get a thumbs up. If you hate it, you get a thumbs down. You can add web sites to its system by simply rating it, so boring, neutral, sites hardly ever get any kind of action. After awhile, with enough ratings from your own, it’ll show similar stumblers who have similar tastes as yours, and you can go and see what web sites they have rated. It’s not just a great time-waster, but it can also be a productive time waster, as it’ll quickly show you some websites in a field and cross connections you may not have thought about. Think of it a sitting on a couch and mindlessly going through the channels. Except it kind of knows what you want to see after awhile, and only shows you stuff other people like too. Only sites you rate become available for public review, so it’s not as creepy as it sounds.
Del.icio.us is a bit more precise in that it’s a persistent (it stays the same, since it’s not relegated to just one computer, so you can access it from anywhere) bookmarking system. Kind of like what gmail did for email, it is doing for bookmarking (I have del.icio.us on my google homepages now, on every tab, separated out by section). But that’s not quite an accurate description as it’s strength is more social (but does describe the kind of effect it’s having). You can tag my site, glowsticking.com, with the tags, rave, glowstick, glowsticking, and if you want, you can see other bookmarks that other people have also tagged with. It’s great if you want to quickly learn more about Photoshop, for instance. You can quickly see the most popular links, as well as related links.
In short, Stumbleupon is a broad based way of interacting with the internet, while Del.icio.us is a bit more razer sharp in terms of interacting with the internet, but if you don’t use these now and then, I really advise you to start. It can easily raise your perceived IQ point by about 15. Just like what google did for searching for precise bits of info, both of these sites are awesome for a more broadbased interaction with information, kind of like browsing books at a library or bookstore. Except faster and you don’t need a library card or gas money.
