Absolutely. Whenever I have spare time, I go through Hubtivity all the way back to when I last looked and read everything that looks interesting to me.
Of course sometimes too much time has elapsed, so I won't necessarily see EVERYTHING, but I do get to see and read quite a bit.
Why? Because there's a lot of good stuff here and sometimes even the not so good hubs give me an idea, especially if I think I can do a much better job with the topic,
