What would you improve about SeededBuzz?

SeededBuzz only allows you to add ONE site/ONE blog to your profile. What if you have more than one blog and want to plant seeds for both? This can be improved. They should allow for more than just one blog to be featured by each individual.

Seeded Categories are a bit generic and unspecific. Would it be possible to allow bloggers to add their own tags in addition to the ones provided?

I'd like a way to go in a fix errors on my buzzed seeds. For example. I mistakenly put my general URL instead of my permalink. That could frustrate a lot of people when trying to find my article. How do I go in and change it? I've looked. I don't see an edit button anywhere.

I agree that categories are sometimes too vague to really apply. Improving the category names would be helpful.
Might I suggest adding an Education category, for starters? And perhaps something along the lines of "Personal Productivity" (time management, day-planner systems, etc.). In fact, a "suggest a category" field somewhere on the page where we have to select categories for our seeds would be helpful, as it's when we're submitting seeds and can't find the categories we would most intuitively place them in, that we realize what's missing.
