Over my 11 shameful years on Reddit I've made a bunch of tech support posts that I think have been pretty helpful for some people. With Reddit making their results exclusively searchable on Google I'd like to move these to a better place where they can be easily found and accessed by anyone. Is there a good option for this?

I could set up a personal blog but small blogs rarely show up on search engines. Stack Overflow is cool but only does Q&As, not guides. Is there a good platform out there?
