I found this to be interesting and worth reading and making note of what's being said.

I made a killing during the dot.com era.... I'd buy half a million of Microsoft/Dell/Intel/Cisco/Juniper.... in the morning - before noon I was playing golf after flipping them out up .50 or a buck a share...
The only thing that bailed me out was paying cash for a house built in 1923 and gutting it and doing a year long remodel... using the cash that I was flipping over and over. So I was busy doing the remodel and quit trading during the end of that period. Otherwise - my guess is I'd have lost half or more in a manor of weeks.
It all seemed so easy! Every day - every thing went up... but people weren't buying companies - they were just buying hype... and there were more buyers than sellers. Ultimately the above names became real companies and have made money -- but I can give you a list of fly by night dot.coms that were nothing - made nothing - and only counted "eyeballs". POOF! They're gone.
I don't think Alibaba is a nothing.... and I'm not choosing a side here - don't own it - probably won't for no other reason than I prefer income over a "maybe" --- in the meantime - a maybe can make millions --- we'll see how it all plays out.
