Copying my post from DQN
There's one feature that might actually improve textboards. Index the front page dynamically based on the last non-saged post, allowing the page order to be restored after bump spam is deleted. There's not a slow forum around that wouldn't be improved by this. Backend mod tools and the previously mentioned bump spam negation are all that is needed. Ylilauta is one of the few sites I know that actually does this properly.
Do this.
