The StumbleUpon effect is real

The StumpleUpon acquisition rumor is interesting if not a bit weird, but it doesn’t surprise me that they are being taken seriously. They weren’t really on my radar until I recently looked at the traffic reports for my wife’s blog, HelpThing.

She got a massive spike sourced from StumbleUpon referrals which, of course, is relative given her small audience, yet. But it wasn’t an isolated incident, and now you can see here that StumbleUpon is actually a very healthy source of traffic in addition to MyBlogLog and This chart is the referral sources for the past week in which she got a smaller spike on a somewhat older post.

There is something strangely addictive about it, and there is so much room to build interesting discoverability now that they are crossing the critical mass chasm.

I don’t know too many people who use it (well, I haven’t asked many, to be honest), but the ones who do always give you a sheepish grin when you ask them about it. It’s hard not to like after using it a few times, and it does feel like they might be on to something potentially pretty big here.

The next Yahoo! Hack Day to be in London in June

This event should be really good. I’ve been working with the local Yahoo! team in London and their partner BBC Backstage to keep the spirit of the original Open Hack Day alive, and I think the teams there have done that and raised the game significantly. If you are in Europe and oversee Internet developers, then you need to get your guys to this event.

Event organizer Tom Coates posted some thoughts on why this event is so great and what happens there:

“It’s a two day event, starting first thing on Saturday morning and running through to Sunday evening. We’ll have a whole bunch of speakers from Flickr, Yahoo! and the BBC to start us off. We’ll have food—mostly flat—to meet the dedicated needs of our guests. There may be booze. I’m not telling. If you want, you can stay awake all night or crash out in a corner in a sleeping bag. The only requirement or restriction (except for the legal ones, which you should probably read) is that you come to the event and try and build something, ideally using some of the stuff that all the organisations hosting the event have to offer. Did I mention it was free?”
