Hey, I have a linkwheel, for one of my sites, that was created about 2 months ago. Includes 25 web 2.0 properties, and they were social bookmarked at the time. I was wondering does it make sense to do anything to your linkwheel over time? For example, update content on the pages? Do additional linking? What do you do with your linkwheels? Do you build it, and leave it? Or do you make some sort of improvements? Any advice appreciated.
