although I don't develop domains. .org as a gtld has always had a decent standing as a domain extension. It's best used or brought for an investment or development where the subject matter is related to a public service or even just a general information subject with an acceptable expansion into commercial content.
The use of .org.uk (for just about anything) actually really quite shocked me when I first became a member of Acorn. But, then again so did a lot of other things about the UK name space
