As a nice, quick and hopefully fun way to expand the scope of the site and improve our questions and answers, I introduce to you the Graphic Design Biweekly Topic Challenge...
Here's how it'll work:
1. Suggest topics
Everyone suggests topics in answers below.
Suggest whatever you like; it can be something really specific and fun or just a general theme, something you're interested in or something you think the site would benefit from. Just keep in mind the aim here is to improve the quality of questions and expand our scope (the topic obviously needs to be on-topic and have enough interested users to generate the questions and answers though).
Topics that may be relevant to users from other sites could be a good idea (mention the site in your answer and any ideas on how to promote the challenge to that site if you have an idea for something like this).
Keep suggestions to a single topic per answer please. Suggest a tag if you can. Some reasoning behind your suggestion and some example questions wouldn't hurt either (but not essential).
2. Start the Challenge
Every other Friday I'll pick one of the topics and write up a new meta post introducing the challenge for the following two weeks. The topic will be associated with a specific tag so that we can count how many questions were asked (it doesn't matter if it's an existing tag or we come up with a new one, or if the tag is only useful for the challenge, we can clean up tags after the challenge).
3. Get Involved
Anyone who wants to participate asks about the topic. Ask a question (remember to tag with that challenge's tag). We ask and answer as many good questions as we can. Simple as that.
I'll make an effort place some decent bounties on some of the questions asked.
At the end of the challenge, I'll post an answer to the challenge with a count of how many questions were asked and anything else notable (e.g. favorite questions, bounties awarded). I'll also update this question to log all the completed challenges as we go. Then...
Start again on step #2. For as long as we have topics and enough interest.
Feel free to (and please do) add new topic suggestions at any time and we'll keep this up as long as people are interested in doing so. I'll do some analysis on question asking rates etc. periodically to see if this is actually having a positive effect.

Please let me know what you think and start suggesting some topics! Go...
