I would love to see them support TLDs such as .dk, .de, .it etc. That way both me and my clients could begin consolidating domain registration in one place, instead of using expensive and shitty domain registration management services. Harder ones, like Tonga (.to) or Greenland (.gl) would be nice to have as well, but I don't think it's feasible (or possible even) to integrate with all countries.
An even better example, of course, is Cloudbleed, but I guess we've all agreed to pretend that never happened?
You are correct that their CTO has submitted 16 posts this week (not all of them from their own blog), but I don't see the harm in that: less than half of them attract any comments at all and quickly slip beneath the waves.
Also, to be fair, it has been an unusually busy week, as they had a "Crypto Week" during which they announced something genuinely interesting each day, and their 8th birthday was a fair excuse for a navel-gazing post.
