I thought it was pretty funny.
I agree that it is frustrating about the three letter thing because, you know, there are so many things one would want to search about that have three letters. However, such a search would yield so many results as to pretty much render the search useless to the user. Also, you wouldn't be able to perform the search because the server would be in a constant state of being to busy to handle your request.
Normally you can find what you need without three letter searches. If you are creative in your search terms I guarantee you'll find what you're looking for.
Please tell me how I find topics related to PAL video resolution. If I remove PAL from the equation I get waaayy to many answers.
Also IGR. Not many people actually write in game reset in their topics.. Oh and In is a no no anyways.. bah.
PAL Video, PAL Mode, PAL Screen, PAL/NTSC, PAL Resolution...IGR Evox, IGR Xecuter, IGR BIOS, IGR 'any dash name'......that good enough for ya?
I encourage anyone who make an informative post on XS.. to include KEY WORDS in the post. As long as they don't spam it with the WRONG words. 
Like how some sites get google hits by posting somewhere hidden on the main page all the naughty words.
