I think we are at the point of Round 2 of euphoria.
Back in the late 90ies, this happened too.
I distinctly remember there was a stock run up while I was still in college with companies like Netscape, Spyglass, and a few other dot.coms
And then there was a medium correction where the first way of these dotcom companies crapped out… And then there was a second wave of euphoria for a second wave of dot.com companies starting late 1998 early 1999 that was even more crazy than the first wave. This second wave included companies like WebVan, eToys, MySimon, pets.com, Vitria, Ariba, CommerceOne, and all the enterprise software companies supporting all this shit….BEA, Tibco, JD Edwards, Peoplesoft, IONA, etc,etc,etc Somewhere buried in that mess was also Sun Microsystems, Nortel Networks, Worldcom, Ascend Communications, USRobotics, 3COM, and a bunch of DSL companies.
