Recent Social Bookmarking Site Updates.
With the new PR update, My site is a PR 2. When I was a PR 0, I used to see about 10-20 visitors per article the day I bookmarked them with these 3 sites. lately (the last 5 days) though I am seeing almost 100 visitors for each article I bookmark.
Is this because of my new higher PR or because they've changed how many people see each bookmark?
