I really like the forum competitions where you have to hit a certain number/numbers. I know many of my friends here don't like them, and some practice ... less ingenuous tactics to win them, but I always have a blast participating in them. I never check the community more often than I do while a post-number competition is going on. I do like the 3-post-in-a-row rule as well as the "no alt accounts" rule.
I also like competitions where the content of the post is used to judge who wins. Shares and likes can be manipulated, but if Anker is just saying "We're going to pick the best post" that gets me way more involved in making the original post high-quality, knowing that someone somewhere will read and judge what I've done. I do put a lot of myself into the community here, and it's nice to feel like that's recognized, even if I didn't win the competition. For that reason I would suggest "honorable mentions" or replies from @ankerofficial noting which posts were in consideration for winning even if they didn't win.
Along those lines, can @ankerofficial or the moderators @technicallywell and @ndalby get some kind of badge they could award for good posts that live up to the community standards? A lot of us post things that matter to us and that we think will help the community. It would be nice if there was a little extra boost in points (5 points maybe?) if you got a badge awarded by a moderator. Just something that says that someone saw your post and thought it was a good example of how to participate in the community. Then, when newcomers are wondering what's expected here, they could review this list of "good" posts to see positive examples for how to participate here.
