I hate when small specific threads get merged into giant threads. It makes it impossible to keep track of that specific conversation or topic without scrolling through endless unrelated pages. It also kills smaller debates and conversations as they get lost.
This is honestly my biggest criticism and suggestion for this forum. What kind of (potential) new member is going to log onto these forums and be like "oh hey, I feel like reading 112 pages of "all things ...". It just makes conversations disorganized and threads way too long and disjointed.
Why not let small threads die and the interesting ones stay individual? New or casual members find gignatic 100+ pages threads intimidating and I personally find them really unreadable the way they are merged.
