As far as I know no(do you mean the virtual one?), because I was and I didn't see him.
I had a pause of almost one year in Steemit at the end for things of "real" life and I came back about 3 months after HIVE started and the truth is that I have not seen him write much as well(not at all to be honest). Let's see if it appears at some point, I hope so.
Virtual HiveFest? I wouldn't know lol, only been on HIVE for about a month or so but I was on Steem back in 2017-18.
Sometimes not writing is the best option, in all honesty, there are times when I wish I could just flick a switch and be completely anonymous (for the most part) and just vote on posts and read shit, lol.
