Since different altcoins have different technicalities. For example, Monero's technical architecture maybe different from that of Dash. I think It would be good to discuss such in the respective Announcement threads where you might get members interested in the project following rather than altcoin discussion which is abroad place with almost every thing is discussed from airdrops to scam tokens.
The only problem with that is it often gets lost with the twenty different other conversations (while still remaining on topic) going on about the Altcoin, assuming its a popular thread that is. For me, Altcoin Discussion needs more substantial threads, than is X better than Y? which I assume might have been the original purpose of that.
Although, most Altcoins copy one another these days, there's only really a couple that are truly unique.
