The thing is, it's not the polls that have really been bringing in posts, though they have helped a bit. It's the Have You Ever Owned Thread. The polls have certainly brought in people who are looking, but they're not posting much at all. I can see that there's certainly been a lot of lurking based on the 150k views that the "How Much Is My Card Worth?" thread has received over 2 years.
My next intended event was a TCGO tournament, actually. Just kinda feeling meh and also extremely busy offline the next week or so. I've done some events in the past regarding deckbuilding.
As for the polls, you can certainly make threads with polls yourself. It'll need the attention while I'm busy with a business trip all week and then at an anime convention immediately after I get back from the business trip.
More people reviewing decks and posting custom cards they made would be nice, though. I think I'll toss up a postathon sometime to try to encourage that.
And I just remembered there's news out from Bulbanews regarding the TCG. Gonna need to make a thread for that. Maybe I'll do it before I leave for that trip.
