"We actually did this for 3.0 originally, and had to remove it from the code. It's a huge hit on server resources in the end. Everytime you go to install a post, instead of inserting to one table, you have to insert to 2. Every time you change your status, it inserts to two tables. And so on.  \nThe \"index\" table that holds these changes ends up locking due to all the concurrent inserts/updates and selects going on, and then *anything* you do on the forums starts to slow down (because it's waiting on that index table).  \nThe theory is sound. The execution is the difficult part.\n"
