Ok, it doesn't mean anything, at the end. It's almost worthless.
It's the kind of thing you pay attention to when you have nothing better to do with a computer.
Actually, these days, the computer scares me because I can't find any idea for a music a friend asked me to do for him...
We call it "white page syndroma". Transposed in the computer world, it would be "the crappy Windows cards game syndroma". Can't do anything better.
Still, it's warm to my ego.
When you type "sound directory" + free in Google, my website is on the top of the first page !
I don't know actually if a lot of computer geeks type these words in their search engine, but I assume they are some of the hundreds people who visi my little website.
Not too bad for a beginner !
