True. They do have a lot of weight to swing about. It seems petty, but, playing devil’s advocate, I suppose it could be a problem for them if every upstart social network started using the word “book” in their name. Although I really doubt they would have to worry about a serious loss. Internet users may be fickle, by nature, but people — and general populace types, not just tech adopters — are way too invested in Facebook to just up and walk away for some other “book”. This is evidenced by their continued rapid rise in userbase in spite of privacy concerns.
