Facebook may be building a web search engine in addition to their Graph Search

Tech, Web

Why do I think this? I have created some new sites in the last two weeks, some of which I have not publicised or linked to on Facebook. Very soon after publishing new pages, the site has stats from what looks like a facebook crawler on the site. Very interesting. It seems to be much more active in crawling the site than Microsoft or Google. This would suggest that they are collecting their own map of the internet outside of links that are posted within Facebook. What else could it mean than building data for a generic web search engine? Haven’t really seen anyone else mention this so far.
