Taking steps is easy, standing still is hard. How can we help and encourage these users willing to create such blogs? As good intention is I feel like they are going abandon their blogs pretty quickly... On my case, I'm up to reading posts and actively commenting at least twice a week.
Me personally I really don't writing too, especially those times in college when you're pretty much forced to write papers on certain topics. Lately though, I've been writing a bit on topics that I'm knowledgeable and interested in, and let me tell you. I enjoyed it A LOT more. They should just pick a topic/niche that they're interested in. May it be gaming, sports, a certain branch of science, business, you name it.
