Not greek but I definately see a rapid decline in bglo's in my area.
Eventho I do attend a university that is only about 15% African American (prolly due to da fak dat a very famous HBCU is 5 miles down da road). Nevertheless, it has been rumored since I was in highschool that the administration of the university at which I attend was working on eliminating bglo's altogether. And now that I am entering my third year and have been placed in positions such as Student Gov't V.P., I am able to see firsthand that this is true.
But I can't speak for errbody...'specially konsiderin da fak dat I ain' Greek.
