To play devil's advocate on the re-write stuff. That's because new tools are usually significantly better on one or more dimensions and usually not much worse in other dimensions.

That doesn't mean you should actually do it, but as someone who's had more than enough time to get over the new and shine syndrome there's a lot to be gained by migrating as often as needed (ie. the productivity gain from the new outweighs the migration/current support cost in a reasonable timeframe).

Programming tools, techniques and languages are still evolving quickly and even in the same ecosystem I don't use many of the tools and a frameworks I did 5 years ago.
