There are PROs and CONs to almost anything. Maybe it helps if we call them out in one place.
PROs to having a paid membership:
1) Karma. Doing the right thing for its own sake lightens the burden on your conscience. Doing the wrong thing just because you are capable brings you distress. You may not understand it yet, but distress shortens your life. So perhaps paying for membership allows you to live a longer happier life.
2) Networking. Being part of a group that shares an interest and exchanges information without reservation is another of those intangible benefits that you never really understand until you have it. Seen from the outside, this may seem "cliquish", but that is usually a case of sour grapes.
3) Profit. Others have already described the sort of benefits to be had by posting here (improved SEO rankings, random customer generation, not to mention help in making your products the best that they can be and therefore more valuable). I'll add only that being a paid member of the forum that does not sell still profits me, if not financially then certainly in terms of my sense of accomplishment.
4) Education. We each come into this with a certain unique mindset. Being able to share it with others advances all of us. Even the newest maker making the most obvious mistakes might also be helping others by offering a fresh perspective.
CONs to having a paid membership:
A) Money. The money you spend might otherwise buy an additional latte every month, and maybe a premium doughnut. If you aren't into that, then you might otherwise use the money to buy two stabilized wood blocks or a very small piece of damascus steel... but not both.
B) Responsibility. Once you've paid the money you might feel duty bound to extract the maximum benefit, which means spending more time here, and less time grinding.
C) Philosophy. You may be afflicted with the belief that all speech is (or should be) "free", which you translate into costing nothing. In such a case, it might seem "wrong" to pay to be able to say whatever you want.
I'm sure there are more in both categories. The point I'm making is that people will not always agree on whether the PROs outweigh the CONs, and while we might not agree with their choices we would be well advised not to simply assert they are wrong.
I know for myself the big problem was not wanting to seem pretentious. I got over that, and decided to go the other direction and be as pretentious as I could.
In the end, I decided to pay simply because I wanted to support the forum. Long may it be here for future aspiring makers!
