217w ago - The honeymoon appears to be over for Internet Explorer 8 - and it wasn't much of a honeymoon to begin with, either. Just days after the browser's big debut, its market share has fallen a full 28 percent from its peak.

Alternative browsers, meanwhile, have held steady ground, losing no significant number of users to Microsoft's new offering.

To quote: IE 8 managed to break the 2 percent mark within a day of its release last Thursday, according to tracking data by analytics firm Net Applications. It grew slowly over the weekend, topping out at 2.59 percent of the overall browser market at 3 a.m. (EDT) Sunday. From there, things started heading downhill.

With a steady decline, Internet Explorer 8 dropped down to 1.86 percent of the market by Monday morning. It's bounced up and down a bit since then, but thus far, there's been no sign of a second wave of supporters rushing to make the switch.

Compare that with the release of Firefox 3 last summer: Within just three days of its launch, Mozilla's next-generation browser more than doubled its beta share, jumping up to nearly 19 percent of the market.

"I suppose the kindest description of user reaction to IE 8's first public outing would be 'underwhelming'," says Aodhan Cullen, CEO and founder of online data firm StatCounter.
