I keep meaning to enter, but in all honesty it's not a priority for me, and keeps getting pushed further down the list of stuff I need to get done.
I've listened to, and voted in 2, maybe 3 month's competitions though.
I don't feel that the publicity the Composition Challenge receives is excessive. I feel a little pang of guilt whenever I see it mentioned, but that's just me feeling bad for not having the time to participate.
Maybe I need to review my composition/life balance.
