Good news for blogger who are hoping to get some exposure from Digg.com. BusinessWeek reports that Digg is opening up their service to other subject matters besides just tech. It’s not hard to understand why. The tech crowd is fine, but the bigger money in advertising will have to come from much broader audiences like politics and finance.

It’s an interesting move by Digg. On the one hand you have the attempt to appeal to a broader market, but you have to balance the needs of your current readership. If the current crowd is into technology, they may have very little interest in politics.

There’s no word on whether this makeover will involve a new design, or even breaking the website into different categories. It will be interesting to see the application. Digg is already a ridiculous popularity contest, I can just imagine who much of a cess-pool it could be when it opens up to even more fields.
