If you didn't read it in the R&D digest, Anton Gostev has started a Ask Me Anything subreddit.
If you always wanted to ask Anton anything special and didn't find the right place, this could be your chance. Just keep on mind, that it's not meant for support requests and similar:
This is NOT a good place to ask me about tactical stuff such as an advice about your particular environment, help with a support case or with a sales quote. However, if you have more of a global/strategic/tough question and you want my opinion specifically – now you have an opportunity to ask me directly
