I like the fact that it has remained intact since the beginning. Nothing has changed since I first joined in 2014, and even if you look way back, there were minimal changes. It's minimal, functional, and loads quickly. That's its beauty. It didn't have to modernize itself.
I like that many people here get paid to participate. What other website can you make a post from the toilet and earn a few dollars? It's a shame that the quality of content isn't taken into account in these payout structures, but it's still a cool thing. Granted, it could be improved upon a great deal and benefit more users if it were managed by the forum, but it's still the reason a majority of posts are made here and that keeps things humming along as the information base continues to grow and gives users a chance to support projects and products here by purchasing them with funds from forum participation.
It's certainly the only forum I've seen featuring such an opportunity. However, posting quality has severely improved after the merit system was introduced. Those lacking merit couldn't rank up and were rarely accepted into decent campaigns. The altcoin discussion board is more prone to spam posts. My best guess is that it is due to the abundance of bounty campaigns being offered.
I don't really know to what extent of a hysteria posters will be thrown into if all signature campaigns make it a criteria to qualify eligible posts. Those edited will be disqualified. I believe it will cause the type of panic introduction of the merit system caused.
As long as signature campaign managers are doing their due diligence before accepting someone onto their campaign, then it really isn't an issue. Ideally, they should already be hiring quality posters, and editing is something that we all do.
Plus, I doubt many users abuse the ten minute period, since they would've just posted whatever they edited to in the first place. It's mainly used for correcting mistakes, since reading your post after the preview I find highlights more mistakes, not completely sure why that's the case, but I guess it's just sod's law.
I recently created a thread abusing the edit function. As long as you do not post bursts of gibberish in an attempt to edit your posts later, you'll be fine. Myself included, have edited posts well after the 10 minute grace period, either because I found a grammar mistake which I hadn't seen beforehand, or because I forgot to add a tiny bit of information. I am not going to alter the whole meaning of the post, nor will I edit its content a whole day after its creation, but a few minutes after posting it is fine.
