That's a good observation.

• BBSes are often topical that makes them "wash out" over time, since the actual on-topic discussion/information sharing is limited before repeating itself. Because of this and usual heavy moderation, it turns into an echo-chamber of sorts. Hence, the off-topic subforums are usually the most lively ones.
• SA is a general BBS, inheriting most of its flaws. As such, paying tenbux to suck up to the mods isn't worth it.
• Reddit and oh-so-many "karma"-based forums are just jerking it to another counter.
• AIBs like 4chan (and - RIP - textboards) is a mixture of people who understand the purpose of anonymity and those who think it's about acting like a retarded ape. Good boards become popular but then rapidly degrade in quality when this mixture gets too lean.
• Twitter is just stupid by design: take a simple thought and make it fit the line. They even ended up implementing "threads" so the user can share series of deep over-simplified thoughts.
• Group chats like IRC are "in the now", so searching for useful information in the past is like looking for a needle in a haystack.
