One of my projects for the next few weeks is to get my blogging stuff up and running again but with a couple of tweaks:
1. I'll never allow on-blog comments again, ever. The signal/noise was always so poor. I'm sorry that you had a similar experience and the unpleasant odour of drive-by sniping got to you. For what it's worth, I'm always interested in finding new writing on tech topics, and I try to never be mean: I am not unique in this, so consider if there's another way.
2. If I ever publish code, it'll not be on a SaaS platform like GitHub, I'll manage the release through tar.gz/zip files, and if people don't like that, fine. I'm not after pull requests or starting a "real" OSS project. If somebody wants to take that OSS license code and host/manage it, godspeed to them.
3. I will write some code that looks for links back to my blogs, so if something I write is referenced by another blog, I'll learn about it at some point and I can go take a look, and that would be interesting. A long, long time ago there was some automation around this using web hooks that almost became a standard, so I'll look into whether that is a thing or not any more.
In my experience if somebody is writing a blog about something they are normally more constructive and thoughtful than if they are just writing something in a text box while "driving by". I'm OK with those articles normally even if they're critical or in disagreement with me about something.
