When you are evaluating applications to install on your servers, or even SaaS applications, how much importance do you give to the size of the software company that develops and supports the product? Of course a one or two person operation might be suspect. But we debate in-house about whether it's better to go with a big vendor or a smaller one, other things being equal. A big vendor has more resources, but smaller companies can be more responsive. Look how useful ServerFault is, and I believe they have just four people!
So how important is size? Does a 30 person company give enough comfort? 300 person? 3,000 person?
