The recent comeback of the tech IPO is over.

Gone, up in smoke, after the debacle that was the highly-anticipated-b​ut-ultimately-botche​d $16-billion debut of Facebook (FB)

As more gory details and a parade of lawsuits materialize, it is clear that the whole fiasco will likely further discourage investors -- even those big institutions accustomed to risk -- from participating in initial public offerings, especially tech deals.

A small device by a start-up company called Leap Motion lets users control their computers using 3D air gestures, meaning the stylish finger flicks and arm waves associated with the futuristic computers in "Minority Report" and "The Avengers" are coming soon to a device near you.

Here's what you should know about the cool new tech that has the blogosphere hyped.

In the aftermath of Facebook's (FB) IPO, Microsoft (MSFT) quietly launched its own experimental social network called "So.cl" (which it insists is pronounced "social," defying phonetic reason) over the weekend. The software giant calls it an "experiment in open search," and intends the service to supplement existing social networks rather than replace them. What does that even mean?  (Microsoft owns and publishes TechBiz, an MSN Money site.)

Here, a brief guide to the new kid on the block:

Less than three days before Facebook’s ( FB) initial public offering, Chief Financial Officer David Ebersman decided to boost the number of shares the company would offer investors by 25%, said people familiar with the planning. His main adviser at lead underwriter Morgan Stanley (MS)  assured him there was plenty of demand, they said.

That decision by the 41-year-old Facebook executive may have doomed any real chance the social-networking company had that its stock would jump on its first day of trading -- a hallmark of successful IPOs.

At this point, teeing off on Facebook (FB) has become the town carousel -- everyone gets a turn.

Facebook fell down the stairs again to open Tuesday trading, this time stumbling by about 7% before collecting itself a bit. At $33 per share as of this writing, FB is sitting about 13% down from its original $38 pricing.

Which would be a relief to some investors, considering how many people bought in at around $42 when Facebook started trading. For those unfortunate investors, losses currently total around 22%, if those buyers haven't jumped ship by now.

So how’d we get here?
