My name is Tim and I work here; I'm the community evangelist for Stack Exchange and Stack Overflow.
I've been working my way around some of the oldest sites in the network just to see how things are going and ... can you believe it has been over 8 years since Graphic Design entered public beta? And, if you take a look, you'll see that the list of people that really nailed this site early-on are still familiar faces. It's rather remarkable for a paid group of people to more or less stick together that long, much less folks that are motivated mostly by just sharing what they know. There's a lot to be very proud of here.
Investing in anything so emotionally and so heavily doesn't come without cost and that's why I'm dropping in. This isn't edict from the ivory tower, or anything like that; I'd write this even if I didn't work here because like you, I enjoy sharing bits of what I've learned at opportune times. What I want to say most of all is, it's okay to feel tired, and doing so isn't a right one needs to earn. That may seem simple, but I sure wish someone had shared that with me back when I first started here six-and-a-half years ago. I felt like I didn't have the right to feel drained as I worked on some of the most complicated problems our communities were having because I felt like I hadn't yet accomplished enough. I've subsequently learned: that's hogwash, and pretty unhealthy.
This leads me to also remind folks, it's okay to take breaks. Taking a break isn't abandoning anything, it's taking care of yourself so you can take more deliberate and successful care of the things and people you care most about. I mention it because when you see folks struggling to feel okay about how tired they are, well, they're certainly not thinking about taking less-than-permanent breaks.
This leads me to my last point which is try to be appreciative and welcoming of feedback even if your immediate instinct is to disagree with, or even resent it. This is likely to come in the form of "take a break", but it could simply be you not realizing how tired you really are, and how much that's coming through in the way you relate to folks.
Above all, Graphic Design is very much a superior resource in its space because people care so deeply about the quality of answers that questions receive, and everyone is doing a fantastic job. That's it, there's no "but" to that.
I just checked in, looked at flags, chat, moderator activity, comments and saw a very healthy site, along with an opportunity to share what I hope is, a helpful tidbit of experience that I've acquired while working here.
You can feel free to leave an answer if you've got any follow-up, or reach out to me privately (I'm tpost@stackoverflew
just in the present tense) if you have anything you want to share.
Keep doing what you're doing, and thank you for doing it!
