I plan to run a weekly (maybe even bi-weekly) giveaway... and think a separate tab would be both good & bad.
Bad: It's not gonna attract as many eyeballs - I assume it won't be the first thing users see when they log in.
Good:
- A dedicated space for "contest-hunters" that come to dpoll just for the contests. - might even attract more/regular dpoll users as a result if dpoll contests are "easier to find".
- dpoll users NOT interested in contest/giveaways (assumed to be typically lower quality/less "thoughtful engaging" polls) won't be inundated with these polls.
i.e. I think the good outweighs they bad.
