Count me in, I do selfvote a lot and advocating it since day one. I mean, obviously not throwing full power votes on comments. I wrote about it multiple times in the past but I'll try TL;DR summary here:

1. self voting was default at the beginning, it was turned off because was suboptimal as there were anti-bot mechanisms so letting author selfvote at their own selected time was better
2. HP should matter, authors just like curators should want to have HP, why would they want to have HP if they couldn't selfvote?
3. If community thinks that selfvoted post of a given author is overrewarded then that's exactly what we have downvotes for
4. Making selfvotes automatic at consensus level would be pretty amazing because then it will deplete shitposters from their voting power
5. If you think your post doesn't deserve a vote even form yourself than maybe you should reconsider writing it to stay forever on the blockchain? ;-)
