I am guessing that a lot of so called 'SEO experts' use these tools before they decide if they will submit their clients sites to a given directory. There are a lot of SEO's who still think that back links is the only factor
Last month after DP, iwebtool was my second top referer lol. seems people check what my PR0 bidding directory will become after the update, and is it worth submitting to it. I reckon mr G has taken the PR snapshot, and will start exporting it to the tool bar in a couple of weeks...
I know. I asked for a simple link exchange and over 40 people checked my "Predicted" PR ,and then I got a bunch of unrelated link requests. IT's just plain silly.
