REBOL is a powerful software technology (ever thought that you could write a full blown GUI Instant Messenger in
only 7 kb of source code?) designed from the ground up to enable a new era of distributed Internet applications. The technology provides a ubiquitous, lightweight model of distributed computing that operates across all types of computer systems. REBOL is a true distributed computing architecture. Applications and data become distributed across all devices. REBOL is completely device independent, so it does not matter what operating system or hardware is being used. Every system of the Internet becomes an independent resource that can process and communicate information. The REBOL kernel currently runs on more than 40 different operating systems -- everything from large Sun Solaris servers, to Windows and Macintosh PCs, to Linux, BeOS, down to CE handheld devices. And it is here to revolutionize the Internet, by introducing the X Internet (also called as 'XNet') through the REBOL Internet Operating System (IOS).

I have to agree w/ Zsolt Marx (above) -- this thread sounds like 5 of the 10 guys working on REBOL started astroturfing the message boards. Perhaps I will check it out, but the level of ass-kissery on this board has definitely raised my level of skepticism. Also, I would argue that one of the noted drawbacks from above -- REBOL is not open source -- is a pretty key point, and not just a minor drawback. If some technology is going to be the lynchpin of the next generation Internet, do you really want one company controlling it? I mean, I'm half willing to say yes, just because they're not Microsoft, but a) that doesn't guarantee anything about their future business practices, and b) they could very well get bought out by MS, and then it would be the same damn thing. Anyway, I'm curious and I will play around w/ it to see for myself.
