Gaskins is dead-on. This week also saw the IPO of SolarWinds (NYSE: SWI), a networking player that right now remains trading up 10 percent from its opening price. With two more successful tech IPOs in the bag, it's tempting for many to think the IPO drought is over.

Later, in that Reuters report, Bob McCooey, head of new listings at NASDAQ OMX, tried to put things in perspective:

"This shows the market is getting better and there is pent-up demand from investors that love to buy IPOs," he said.

McCooey's certainly right on his second point, chiefly because there's never a shortage of investors willing to throw their money away. OpenTable's a godsend for the sort of folks who thrive on eking out prime reservations at big-name eateries (think: reservations at Dorsia) but who lack the time or willingness to do it the way it's always been done (read: endless phone calls or two-month waits). So, it's a good thing, and another sign that the Internet can make our lives more efficient. Bravo.

But let's not blow things out of proportion, either, OK?

I'm not among those necessarily saying that OpenTable is overvalued, but I am saying that it's worrisome to even seriously consider that it -- and SolarWinds -- warrant the optimism they're generating.

Take a second to look at OpenTable's financials. And note how few shares it actually sold yesterday. Overvalued? Maybe. Overhyped? Certainly.

As for OpenTable, well, it's probably going to do just fine even when stripped of all this interest as a potential herald of a wider Wall Street turnaround.

"Open Table is a veteran of the first dot-com boom and bust, having been being founded in 1998," Therese Poletti wrote over at MarketWatch. So, hopefully, the company has learned to focus on its business and ignore the sometimes deafening buzz that emanates from a hungry Wall Street."
