Thanks for the information about the pool.  I just got my BTC airdrop and went ahead and split my SEMs up amongst the five validators in the pool.  Though I did notice of their validators says that it has been offline for a week ("madrid").  I wonder if I should unvote those.

I also went ahead and registered to be a delegate as well.  I have nowhere near enough to become a validator, but it should be a fun test to see if anyone actually votes for my delegate out of the blue.  (I don't know if it is against the rules or not to mention my delegate's name, so I'll leave that out just in case.)

Will the UI let you get to a point where you can actually lock your entire SEM balance?  I'm wondering if there are safeguards in the software to prevent you from doing it.  If you lock your entire balance, you would never be able to pay the transaction fee to "unvote" and you would be stuck until you actually acquire more SEM.
