Each year I run a cover contest for the SPFBO entrants. Each blog chooses its 3 favourite covers from their pool of 30 entrants. The 30 favourites collected from the 10 blogs are then voted on in separate ballots by the bloggers and by the public.
The public vote is of course a bit of fun and subject to all the issues of brigading and cheating that online polls often are - though our anti-cheat software is more effective than the raw poll results might lead you to believe.
We did this in 2020, 2019, 2018, 2017 & 2016 too.
