I agree with this. Those of us who have merit to award tend to not think of it because this is a new thing and you know, we're all dinosaurs. With that said, I am trying to be conscious of awarding merit when I see a good post. Here are some things I look for:
1. correct spelling and grammar
2. some truly useful information. Even if I don't act on it, I can recognize that it's useful.
3. a good question asked in an intelligent way
I will not award merit to posts if I see the following:
1. asking for merit
2. poor spelling and grammar
3. nothing worthwhile in the content
4. questions that could be easily answered with a little bit of research
Keep in mind that not all posts are going to be "merit-worthy," as some are just parts of discussion and those are important too. But at some point as you learn and grow in this industry, you should have some valuable insights to offer, some good questions to ask that others will appreciate. When you get there, you probably will be much less concerned about your merit or rank on this forum as you will have transitioned into finding your place in the industry as a whole, networking, joining teams, contributing work, and all that good stuff.
And it goes without saying, please don't ever PM anyone asking them to send you merit. If that happens to me, I'll simply click the ignore button on the sender and be done with it.
