I'd say their problem is not exactly solvable by only choosing a
database :D
They, like Facebook, have the problem of "fanout", where a single piece
of data goes into thousands of different user pages. Whatever they save
in the raw data access operations will probably be relatively small
compared to the horsepower needed to combine pages from all these
fleeting data pieces.
Good point :) I'm still sure it would work much, much better though.
However, I'm just glad that's not *my* problem to fix.
