Summary: discussions are often too negative, and when they’re not, we still have better places for them.
Discussions on the Internet often are negative. Widespread Internet access gave some people confidence that they can do whatever they want, even have fun at the expense of others. It’s bitter when that kind of people are around, it’s pointless to talk to them, so I just cut communications off (though not entirely—you can still read my entries, right?)
People misuse them. Comments are often useful: they contain typo corrections, suggestions, new ideas etc. But just as often, feedback degrades into helping forum, offtopic, or flame war, and that is definitely not what comments are for. Which brings me right to the next point.
We have better places for discussions. Hacker News, Reddit, Google+, whatever—just use what you like. Come here to read the entry and then go spread the word. After all, search engines are the entry gates to the Internet now. It doesn’t matter anymore if you comment on my article here or elsewhere—your feedback still can be found.
And that’s all there is to it.
P.S. If you want to discuss some post with me personally, check out About page for my e-mail.
Drop me a line! (wonder where’s the comments form?)
