StumbleUpon milestone - five million users, five billion stumbles

I am a big fan of StumbleUpon. I believe it is very underrated in the blogger community on the amount of quality traffic it can get you.

Sometime today, StumbleUpon will register its five millionth user. That’s right, 5,000,000th. (At the time TechCrunch reported this today it was at 4,994,826 registered users). Even though that number is a bit meaningless because it counts all users that have ever registered with StumbleUpon, it is still indicative of the sheer size of the service.

The service will collect its five billionth stumble within the next 30 days. Users have already stumbled more than one billion times so far this year.

Those are some amazing figures!

Most folks look StumbleUpon as a socially-powered discovery engine rather than a search engine, but personal discovery and search may be colliding. During a recent speech at the Next Web conference, StumbleUpon founder Garrett Camp noted:

Personalized search is just getting started. I think personalized crawling will start too. Crawlers now are trying to create the biggest map of the web, but implicit filtering and intelligent agents—that is where search and discovery will meet. My query log isn’t actually representative of what I want on the Web.

What this means is that by increasing their Stumble index, StumbleUpon are actually purifying search results. We already Stumble! stuff that other folks on StumbleUpon think is good in the categories of our choosing. It shouldn’t be hard to use the same algorithm in intelligent search engines.
