I mean OK, I guess. I can find plenty of stuff on it, but honestly, I'm not even sure what the point is.
Like every article is an opinion article for the most part. I can post my thoughts on the flea flicker and have it online in 30 minutes if you'd like. The only thing really factual about it is the definition of it.
I see nothing in any short search about the frequency of usage of the flea flicker, how effective the flea flicker is, or really why any team should even consider using it. If you find something that calculates like mathematical probabilities of its success, how successful teams have been at using it, etc., then those articles are worth reading.
