My advice if you want constructive feedback is to ask on SMWC's IRC channel. Usually you can find a lot of helpful users who are willing to critique your work, and can also be a signal boast for your work itself.
Honestly, it did a great job at giving SMWCentral unintentional publicity. It came out just as creepypastas was reaching peek popularity and everyone mentioned it came from this site as well as quite a few linking back to that original thread Adam made.
I think I remember one youtube video where a person actually got in contact with Adam to get to the origins of the hack or something.
It's kind of interesting that ideas for the Wii U Gamepad just naturally evolved into just off TV play, considering games like Nintendo Land and Zombi U did make good use of the Gamepad and things could have gone more in that direction if the Wii U really took off like the Wii did.
It's also interesting that living room off TV play wasn't shown off in the Switch reveal ad. Perhaps it wasn't shown off to minimise people getting the Switch confused with a upgraded Wii U due to how heavy off TV play was featured in Wii U promotions?
I remember when I first started using internet forums, I went on a Sonic forum and immediately started making trash threads and posts about how Sonic sucks and how Mario is better, ect. Years later, when I was more active on the internet I was searching my Username and came across those posts and felt bad about them. I decided despite being years later then I would apologize and did just that.
I like when people apologize and take responsibility for themselves on the internet because there is nothing forcing you to do so and it's always seen as a breath of fresh air with the usual drama internet forums create. Like Gloomier said, it's a sign of maturity and it's hard not to respect that.
PC game development sucks massively. You are almost always guaranteed to have unexpected problems after shipping and unless you have a similar enough PC to test on, it's hard to even debug the problem.
The best you can do is to prepare for unforeseen problems beforehand and prepare debugging tools for customers to give if they are experiencing problems as well as to expect to dedicate a month after release to just sorting every issue that comes your way out.
