Twisted and Scrapy are getting ported, and the community is moving forward. But this is not happening because of a miracle - people are making it happen. My point was not that Python 3.x is bad (I think it is good), it was that community still needs help, that writing alternative software is not the best way to do it, and that there are still reasons why writing new Python 2.x code is easier.
Praising 3.x won't make users switch if they need some unported package, and bashing 3.x won't make other people's lives easier either. So let's help twisted, scrapy and other modules to become 3.x compatible.
Scrapy reached an important milestone recently - its test runner can now run tests under Python 3.x; test runner was the main reason why porting haven't really started before. If anybody wants to help then ping me kmike84 at gmail.com, or check https://github.com/scrapy/scrapy/pull/682, or go to ScrapingHub booth at PyCon and talk to people there.
