Google has apparently acquired yet another company – Instantiations. This is a provider of Java and Ajax development tools.

As MG Siegler (who first reported the news) points out, the company is known for its Google Web Toolkit designer, which is likely the reason for the acquisition.

Instantiations greets its site visitors with the following message:

As you may have read about by now, Google’s Matt Cutts participated in a fairly lengthy Q&A session at SMX Advanced in Seattle. One interesting question that Matt got was about how webmasters should deal with display:none and AJAX without being penalized by Google.

Google has long maintained that AJAX is the future (and the now) of the Web, and even refers to the click-and-wait method as "the yesterweb." But for developers, AJAX is a pain, especially when debugging for browser quirks. Those struggling, then, may be happy to know that the Google Web Toolkit is now out of beta with version 1.4.
