Tech bubble? Yes. As bad as 1999? No.
"And your bank is involved in this game right now. They are taking cheap money from the government and giving it to fuckwits in the hope of discovering the next Geek Pie*"
Mine's not. I am with a local bank. MOST banks were not involved with this. They did not do anything with these stupid credit default swaps, didn't lose their ass on stuff like that, so they did not have to whine to the gov't for a bailout (which those banks should NOT have gotten -- they should have been allowed to go bankrupt, competent banks would have bought the mortgages and accounts at firesale prices, strengthening the competent banks. Free market in action.)
Is there a tech bubble? Absolutely. There are, again, loads of companies that are providing service with little plan for making money, and yet valued at millions, 100s of millions, or even billions of dollars.
HOWEVER, is it as bad as the 90s? I don't think so. In the 90s, there were companies like WebVan, which would buy your groceries and deliver them to your home with NO MARKUP (assuming they'd somehow make money with enough volume), companies that'd ship 50 pound bags of dogfood (ignoring the fact the significant shipping costs outweigh any savings compared to just buying it at the store), all kinds of services that cost REAL MONEY with no charges to cover those expenses. The plan was "we are losing money on every single customer, but if we get A LOT of customers, we'll somehow become profitable."
Now, most of these bubble companies are massively overvalued, but social services can be run very inexpensively (how much computing power does it probably take to generate a tweet? Not much. And the humans generating the content aren't paid at all), so it seems to me even though banner ads don't pay much, they may be able to make enough from ads to at least be marginally profitable.
