I've been noticing this flaw in Brilliant's follow feature since about a month. Every person I follow doesn't show up in my in my 'following' list the next time I am here and I have to follow them again (I know there's an upper limit of 100 people that'd show up). I have followed many people more than 3 times now. E.g. I'm following Paramjit for the 3rd time I'm writing this note. It's time the brilliant technicians of Brilliant ought to do something about it.
