Slashdotted, The Wall Street Journal reports:

'Zimbra's chief executive, Satish Dhamaraj, says that when he started his company in December 2003, "I really thought that Ajax was just a bathroom cleaner." Now his San Mateo, Calif., business has amassed $16 million in funding from venture-capital firms including Accel Partners, Redpoint Ventures and Benchmark Capital, the firm that famously funded eBay Inc. Peter Fenton, an Accel partner, says Ajax "has the chance to change the face of how we look at Web applications" and could boost technology spending by corporations, because Ajax is also being used to develop software for big companies, not just for consumers.'"

there is many interesting comments on the topic also, but is AJAX is a buzz ?? yes it is, I don't see anything wrong with that. Is AJAX good ? yes many users are happy with new AJAX based applications. Is AJAX more difficult for developers ? I guess yes it is too, but we can find solution for that. The most important for IT companies is to create AJAX applications which could generate revenue and that's what we're doing.
