Some unofficial advice meanwhile:
I like your post (I'm a mathematician too), but I think that you are posting to often. Posting every day will cause fatigue to the community and your post will not get traction. My advice is to post the new stuff when it's published, and post the old stuff only once a week.
Also, the first and second posts of your site got a lot of upvotes and comments. We somewhat expect that the author replies some of the questions in the comments. (Not every single one. Some are bad, some are repeated, ..., just the ones that you like and think that are interesting.) It's not mandatory, but it buys a lot of goodwill from the community.
