Link Builder Pro - Free Edition looks pretty interesting. Unfortunately, it's Windows-only and I am not that interested in starting up VMWare.

The main features appear to be:

  • Automatically create link-wheels from high-authority Web 2.0 websites – Effortlessly dominate the entire first page of any search by instantly creating wiki's, hub's, lenses, and blogs at the highest PR web 2.0 websites! (WordPress (PR9), Squidoo (PR8), Hubpages (PR5), Tumblr (PR7), and LiveJournal (PR8).
  • Automatically create accounts at the hottest user-driven websites – With a single click you can create accounts for all these websites – and automatically click the verify links in all the emails!

If someone has a bit of time and could use some free links (and who couldn't), this might be a good tool to give a spin.
