I just realized we have to get rid of the blogrush widget from our sites (not wonder it was not showing up the last few days)
BlogRush had one big problem - a focus on categories. Blogs generally are not as strongly themed as people want to believe. So, you get stuck in the "finance" or "celebrity" category, so a post your make about charity never has a chance for breaking out on the BlogRush network. Contextually relevant linking will fill the void (if there is one) left by BlogRush.
Disappointing news. Even though others may disagree, BlogRush was a valuable service for bloggers looking to get a kickstart. As the owner of Publicity Wheel, I'll do my best to avoid the same issues so we don't suffer the same fate.
