No, but I do avoid "articles" on Github pages if they still have the format of crankydev.github.com. I don't know why, but they all follow a similar format. I mean, buy a domain name and map it, right?

As for Medium, folks here have it right. I don't avoid them, but I go in 'eyes wide open'. Any place that allows super-easy 'publishing' should be viewed with suspicion. Editors are actually GOOD things. So, pretty much that means No Facebook Ever.
