Don't Contribute Anything Relevant in Web Forums Like Reddit
[…] as soon as you're helping somebody solving an interesting issue, summarize your experiences with something or write anything that might be cool to be around in a couple of years as well, you do provide potential high-value content. My message to all those authors is: don't use web-based forums.
TL;DR: all of the content of closed, centralized services will be lost in the long run. Choose the platform you contribute to wisely now instead of learning through more large data loss events later-on.
