Together with Brendan and other subscribers of InsideFacebook, we made a series of experiments to check how it works. As of Jan.17, the results are negative. Nothing from our tests appeared in Google as a result of crawling the comments. The whole discussion, however, has been "leaked" through another website, which grabbed our comments from FB and pasted them as a plain HTML.
Brendan pointed out that:
- InsideFacebook uses an older version of FB plugin
- It may take time to Google to crawl all comments
- There are comments from other sites that have been indexed by Google
So, this is not the end of story. Stay tuned.
