Re:The best Flex alternative no one's heard of... (Score 1)

FWIW-- InfoWorld Labs came to the same conclusion... awarding TIBCO GI "best open source Ajax toolkit" over dojo, GWT, YUI, and all others. (http://www.infoworld.com/slideshow/2007/09/116-best_of_open_so-4.html) Upsides of TIBCO GI: Gobs of smart Ajax components and visual rapid dev tools for them! Fast to build Ajax apps...usually business productivity type apps. (Was first released in 2001! Yes 2001 before Mozilla was even a word, less RIA or Ajax). Loads of documentation and resources -- all free under BSD license. (not GPL) Downside: Not for everyone, nor all things Ajax. GI's focus is on apps that are used by business users (thus only IE and FX support now, though the source repo @ http://gi.tibco.com/ has a Sarafi build going that works pretty well in the Webkit nightly build now). With IE and FX you get 99.9% coverage amongst business users, and with Webkit/Safari/etc... other non-business uses may be imminent as well. No Lynx support though ;-) Bottom line: One of the best kept secrets for building Ajax business apps, portlets, and ajaxlets, with rapid development from reusable Ajax components and services (as opposed to adding some Ajax here and there to your HTML pages).
