Sure, this is a great forum if you compare it to those, but that still doesn't mean anything. I can't see what's so hard about just scrolling past the lame posts, though.
Here's a list of things to avoid:
1. One word posts. They usually contain things like 'lol' or 'kthxbi' or variations
2. Posts consisting of just a quote. They normally don't add anything that hasn't been said before
3. The Off-topic forum. 'Nuff said.
4. Petitions. The available alternatives will just make you angry
5. Obvious flamebait (most posts by me)
6. Stupid lists (lists of things to avoid, for example)
7. Meta-jokes
8. Any topic that isn't posted by badspot or the beta team
9. Lists that repeat themselves for comedy value
10. Meta-jokes
Learn to quickly distinguish these and you'll have a more pleasant social experience on the blockland forums.
