There'll be massive drops some day. Tha vast numbers some are buying will show that some have no value for endusers.
Businesses come and go. Most last less than 5 years, so it could be that seperate entities will vie for the same names on occasion to keep some market there. We'll see.
Point is, there are threads showing that some are just trying to buy all of this or that. And it could prove that less than 5% of any portfolio is worth anything at all.
Not good at explaining myself sometimes, so let's rephrase.
When YOU want something 'tangible' and Google for it, do you type gibberish into the search box?

I mean REALLY.
Without a lot of marketing and branding, do you type 'games.com' into the address box looking for games? Or just type sdf3x.com hoping to find games?
I personally think a lot of these 'hits' being reported are domainers coming up with gibberish ideas find that one is taken. So they, the idea guy, will go to the site to see what's there. And there are a lot of domainers.
Another example. I got a WW Domain site. I asked around to locals here to see what they would search for if they wanted to register a names for themselves. 95% said they didn't have a clue what to search for, in any way shape or form. Most go on the web and look up spellable stuff OR what they've seen marketed on TV!
Hope this gives you the gist of what I'm saying.
