First off, thanks again for everyone's contributions up to this point. While I've been researching what ads might mean for the site, folks have donated 2/3 of what I was seeking for a year's worth of operating revenue. The need for ads for the next year has nearly been taken care of just by having this conversation. You guys are the best!
As for the location of the Donate button, I threw it down there intentionally because I wasn't trying to beat it over everyone's heads. I hear that putting it in the header would give it a lot more visibility. And maybe that should be where it lives. I just didn't want it to be one of the key focuses. It needs to be usable, but not in your face every time you come back. That was my thinking at least.
Thanks again to all. This has been a very heart warming start to the new year.
