I think you guys are digressing from the original topic here. I'm not talking about it MarketPlace should have $0.00 or non-$0.00 plugins available, I'm just talking about the usage of word "free" at Liferay.com site because it denotes 2 different things and can confuse users like you guys are right now.
"Free" in open source community is used in something like freedom of speech. "Free" in commercial transaction is used to mean $0.00. Liferay.com is a commercial open source company (COSS) which means Liferay.com does a commercial transaction with development based on open source community model. There's nothing wrong with that because I think most of us here is in it too.
However, the point is if we should use a WORD that can cause confusion and create argument. From the look of it, you guys are getting confused too because you seems to be talking about whether commercial open source is good or bad. I'm proposing it's better to change the word "free" just so we don't get into this kind of argument because it really hinders commercial open source market.
There is a danger that it is going to be fully polluted by Hello World / Click Me - style applications, instead of having a limited (initially) list of robust business applications, developed, maintained and supported by responsible vendors.
Liferay is an open source project. I don't think it should limit who and what others do. That is, the choice should be "free" (as in freedom of speech :-) ).
Nevertheless, I think you've brought up a good point. It may be good to have a facet search facility to filter by price range and developer and have category for sample and tutorial.
