I think it depends on the aim.
If it’s “I love Claire but my cousin just used it. Help me come up with alternatives to add to my list that still feel simple, classic and feminine” then that’s more Name Advice.
If it’s a more “aesthetic” post along the lines of the classic 
Then it’s more Name Discussion. I think there’s always going to be a little bit of a grey area between these two categories and we’re not going to be super-militant about policing those kinds of cases.
As a general rule: anything more specific, more realistic (whether for now or the future or just for building a concrete list of favourites) would be Name Advice, whereas anything more abstract or aesthetic (collecting names for themed lists, general vibes, etc.) would be Name Discussion.
I’ll add that to the About blurb, good idea!
