Much like Perl, English is context sensitive. Things like "few" and "many" are relative frequencies to other possible activities you do. To someone who reads a lot of stuff on the web, a "few" blogs might be 5. But to someone who reads almost nothing 5 would be "many".
The purpose of the poll isn't to quantify the number of blogs people read. (If it were, the poll would list numeric options.) Rather it's objective is to measure the perception of the relative personal importance of blogs among the monks. "How many people feel like they read a few versus many?" is fundamentally a question of feelings, not metrics.
