The site is interesting but i think it's a little be dangerous. If your site is accepted suddenly in all these directories you can be marked as spammer. For directories you must have more Titles and Descriptions if you want to make a good job...
yes, it's kinda Dangerous and bad for website reputation, i prefer the Natural Way , even though it's Slow but You Post at a good Web direc tories and you get a Quality Traffic...
Thanks for this offer: but I personally think that such think will not help much in SEO. The backlinks that one may get from this, will [most probably] not be quality backlinks.
