I’m swamped with work. I can’t yet talk much about the work I’ve been doing until we go public, but it’s a cool project, although its coolness may not be immediately obvious at first.
Meanwhile, I have been rather slow to answer some emails. Here is what you need to do to get a fast email response from me: present me a viable option that allows someone other than me to do the work. For example, if you want one of my open source projects changed, the best thing to suggest is that you will do the work and all I have to do is review a patch. (Ideally, include the unified diff in the email so I can review instantly.)
