I think you got at least the following things right: * when a project has extremely high performance requiremets, rolling your own often makes sense. * some frameworks do make really bad long term tradeoffs in the name of getting started quickly. (ironically though, I don't think any of the frameworks you listed fall into this category) * if you have something that you're guaranteed is only going to be maintained by yourself (ie your own blog) then a lot of what you've said becomes "not wrong" There are probably other things, but those are the two that come immediately to mind.
