From the blog post, describing expectations that webOS will have a small number of committers:
"""(As an example, Linux has thousands of users, of whom only 2.5% are developers or contributors and fewer than 100 are committers. So, the project may have many, many users, but it’s the PMC and the committers who determine the project’s baseline.)"""
Linux users are measured in the thousands? That seems like an incredibly low estimate... (Of course, that may be a case of selective perception on my part, being an LWN reader and all.) It also makes me wonder how Red Hat was able to employ 3,760 people last year
