Yes, I know, old news, Reddit switched to python an year ago, and there's even a whole c.l.l. thread on the topic. But I haven't read much about it, and find that I'm writing stuff that essentially adds no value: implementing a poor wiki when I could have an open source one that has been battle tested. There is functionality I need that the current crop of wikis don't provide so well, so there is genuinely a need for adding functionality. But that doesn't mean I should be writing a wiki in lisp. Even if it means I get to have fun hacking up new ways of manipulating XML.
Certainly, there are many tools currently missing from the common lisp world for building applications. I want to write some of them. But to fail to develop an idea because I have spent time writing tools is irresponsible. There's only one reasonable way I can see going forward: to do both.
