This post documents the result of the case study and shows that some social bookmarking sites are much better at getting indexed than others. One caveat to this case study, is that fact that I directly linked to each entry from the original post. This may have helped the entries get indexed faster than they would have otherwise. Here are the results based on Yahoo's site explorer:
- StumbleUpon
- Digg
- www.lensroll.com: Indexed in 10 days.
- www.squidom.com: Indexed in 2 days.
