Oh my problem isn't that at all. I have no problem writing endless amounts of crap that no one will ever read. It's just that I really care about my writing, and I want it to have a perfect home. So I'm constantly writing and rewriting blog engines.
In this case, the perfect is the enemy of no one. A blog engine is the one side-project that I don't just hack. It's my one and only place for writing pure, elegant code.
And I won't let myself write at length again on someone else's platform until I get this exactly right.
Everyone wins: I don't clutter the internet with inane crap; you aren't tempted to read it.
If I ever decide to start publishing my writing, the best part of it will be the code that presents it.
