Bitcoin Discussion invites the most spam, you're right. I think that's why it's hard to gauge for post quality when you're viewing a thread using Bitcoin discussion because quality replies by people who aren't brain dead are cluttered with lower level members with broken English spamming 1 liners.
Totally disagree with you here. There are plenty of legendary members which just spam one or two line nonsense. I went to Altcoin Discussion, clicked on the first megathread I saw (this one https://bitcointalksearch.org/topic/altcoins-future-5165503), and Ctrl+F for "legendary". Here are some of the profiles I came across in the space of a few pages:
https://bitcointalksearch.org/user/dimox-407887
https://bitcointalksearch.org/user/allwelder-162975
https://bitcointalksearch.org/user/seleme-22145
https://bitcointalksearch.org/user/letyouearn-358450
https://bitcointalksearch.org/user/voteformeg-148225
https://bitcointalksearch.org/user/stripykitteh-101432
They are all spammers. It took me a total of under a minute to find these 6 profiles. There are plenty more.
Okay, fair enough, you got me here. Surprising to see such shit quality posters that are legendary but I don't browse altcoins at all so that's probably why I have a skewed view. Legendary members in Bitcoin discussion, meta, and P&S tend to have great discussion value added by legendary members so I'll leave it at that.
Huh? Well, didn't know that. I was under the impression that went you send merit, your overall merit score decreases unless you are a merit source. My misunderstanding.
Almost everyone (theymos included) has agreed that while airdropped merit could/should decay, ranks should not.
Good, but like I said the problem still persists that members can be active in forums that are cluttered with spam, ie Bitcoin discussion, where valuable posts are not merited because they aren't seen enough. I don't think we should leave it to chance that good quality posts are seen by people who will eventually send merit in a system where merit becomes decayed.
I will concede, though, that the initial merit airdrop seemed fairly generous and that it doesn't allow newer members to catch up efficiently.
