does Facebook show the market trend?

As you can see from this graph Comscore, Facebook knows another year of high growth. Should we see this growth in a change to come, a new trend in 2010, mass migration of Internet users to a social or should it simply that the world needs to share, exchange and thus indirectly from use of tools Social?
The trend in 2010 will certainly be social even though nobody knows who will be the big winner at the end of the year …

I take my choice and I think that 2010 will be social and community.
