I've noticed that the number of sites I have is starting to grow. Things are starting to get a bit unwieldy. Then I thought, why don't we have a way to organize and tag the sites?
I have #personal sites, I have #client sites, then I also have my own #tutorial sites(usually cloned from others to help me remember how to do things). Not to mention genre sites such as things like #finance, #sports, #photo types of sites.
Being able to organize all my sites and finding the ones I am looking for quickly is becoming ever-increasingly important.
