Do you see small orange blocks in the comments area?

I simply entered   #OMG     #LOL     #FAIL   into the comment submission field.

After posting the comment with these hashtags, each one of them showed up as a separate orange block of text. Clicking any one of these orange tags will take you to a global, aggregated thread for the designated tag. They appear to be working throughout YouTube now.

If you want to try it for yourself, you’ll need to place a hash symbol directly before the known acronyms in CAPS; the feature doesn’t seem to apply with lowercase characters. Apparently,  #FTW  works, too.

Kinda neat, eh? I have no idea if they’re going to be expanding this to support every popular keyword, but ATM, it seems to be for these popular acronyms. I don’t know WTF they were thinking, but I (for one) appreciate the feature!

If you discover any other orange’d tag there, let me know!
