A framework is useful because once you learn it, you can apply that knowledge across a wide range of projects. Not only that, but once there is intro documentation for it, the knowledge imparted can help people be several miles down the road of understanding the structure of a many projects. For this reason, the biggest thing I look for in a framework is solid canonical introductory tutorials that help someone build a solid mental model of the framework. This means that even if the number of developers is currently small, it will grow fast enough that I won't worry about hurting my ability to hire down the road. It is especially useful if the intro tutorial teaches automated testing. Then I'm going to be less worried that tests are an afterthought rather than something that is written alongside the feature.
