Yes & no. INHO a girl should have been visibly active recently. I don't care if the girl only posts in her own thread or on the general talk board as well, but I do believe she should show some interaction with her fans (& not just post advertisements on the general board).
Still, since we can vote for multiple girls in the 1st (few) round(s) I'm probably going to vote for the truly active members as well & if they're still in the race when the girls I physically like best are out of the race, I might shift my attention to them.
Anyway, it depends on how the contest develops.
