Since Robotics.SE doesn't have any mods yet, I'm posting to you all directly.
What are these hats you speak of?
Last year around Christmas time arQAde had an awesome promotion in which they awarded hats for gravatars for completing basic tasks around the site. If you don't remember it, here is a link the promo from last year (and another!).
This year, SE is planning to run it for everyone because we all love hats, right? Right?!
Why are you making a meta post?
In order to get this awesome hat promotion, we have to opt in. That means acting on this meta post: voting it up, answering in the affirmative, positive comments, and/or just directing positive energy this direction!
HOWEVER: this promotion is optional for sites, and/or individual users. If you all do not want this event to happen here, feel free to voice that opinion. Users who with to opt out will be provided with an "I hate Hats" link to remove the presence of hats from their view of the site.
I think this is a great opportunity for Robotics.SE to grow and get even more awesome content as we head towards gradumatation. Plus, it'll be a lot of fun!
What if I want to know more?
Please let us know what you think -- this is your site and we want to do things that you feel support the community here!
I'm happy to answer any questions in comments/answers. I'll do my best to be as forthcoming as I can without giving away too much!
