It's been like this with Ruby since certain developers have been pushing harder for 1.9 adoption. A new developer is gonna pick the higher version number, cos higher version means newer. They're then gonna wonder why some gem doesn't work :)
to be fair, there are lots of very real advantages to 1.9. the development community finally seems to have collectively decided to take the plunge, and let the gems catch up, rather than waiting around on 1.8 forever.
Want to try model airplanes ? Get ready to spend a couple of days just to figure out the various materials, radios etc
Want to try computer assisted music ? Which plugin ? Which host ? How do I write music with this, etc ?
You could even rewrite the article for Java a few years back at least (should I go WebLogic ? WebSphere ? TomCat ? Struts or something else ?).
