I've moved my compiler online and opensource after working on it for 2 years in private.It currently is in a state that should be good enough to start make it self compiling.
A quick look at the Ohloh statistics show that the project is missing source comments, which is completely true :) Also Ohloh seems to confuse .pluk files with xml or something.
The experience of the previous pluk language project ( http://pluk.sf.net/ ) shows that putting something online doesn't mean anything further will happen. But I hope it can help me build better software and make it easier to discuss language features with other compiler developers.
