I sympathize with the OP and don't mean to be derisive, but really there is so much open source software to be done, so many niches and gaps and itches to scratch (I currently am writing three projects for which I see little to no "competitors"). And yet his major projects are a plugin system and a static blog generator. I might be coming from node.js here, don't know the status quo in Python, but even as JS is a much younger cohesive community, there are a TON of people doing their own versions of what the poster is doing, in fact they might be among the most reinvented applications out there. And there are clearly many winners already. I love doing developer tools too, many of my itches revolve around them, being a developer, yet I see many problems that aren't seeing as much competition. A good execution on an area open source lacks would not go unappreciated.
