I wanted to point out that Brendan Eich from the Mozilla Corporation left a thoughtful comment on my post about Mozilla and Thunderbird.
He mentions about Mozilla, as platform and the work with Joost, which also incorporates the use of RDF. I was critical last year when Mozilla dropped use of RDF, though I've since become more sanguine about the issue.
The whole comment is a good read, but Brendan did make a comment on the perceived 'pragmatism' of the decision to find new leadership for Thunderbird I wanted to repeat here:
Pragmatism of the Mozilla kind rubs many people the wrong way. Why shouldn't we invest liberally in various dark horses and lost causes, such as our old RDF code or an upgrade to it, and even take the footprint (download and runtime) hit of including such features? I think the answer has to be stated bluntly: because we'll fail if we do that, and then the Firefox lever against Microsoft and anyone else with large market power and little concern for the Open Web will have an easier time.
