Of course, one of the most interesting parts of the README will be the section describing and illustrating why/how your system is both different from and better than other templating systems. And when it would be advisable to use it and when not.

If after writing the README you still think it's a better system, by all means post it here. Then if the negafabulatorists don't succeed in depressing you about your system, *then* you can do the rest of the work to publish.
