I used to sell things for a living. One thing I remember is that there is a tremendous gulf between free and a dollar. In companies, you can’t spend a dollar without having to justify it to someone, to make a case for it. Everyone wants to know who the vendor is, how long they’ve been around, whether we can trust them, and whether what they’re selling is worth a dollar.
So, although your offices are crowded, that actually doesn’t provide me with any security that other people have thought things through and decided you are a good bet. For all I know, they could decamp tomorrow for some other hot, free thing. This feels like fashion, not business, and it’s going to keep feeling that way until you can show me some tenants who actually pay, not just squat.
[The irony here is that this was posted to posterous, which was just bought by Twitter, and which everyone suspects will disappear before too long. Twitter purchased them for their talent, not their product, and business dictates that they’ll shut it down at some point relatively soon. But @raganwald really makes an excellent point about all see services. If you’re getting something of value, and your not paying for it, you must ask who is and why. But never consider a service for which you don’t pay yourself reliable. It’s not.]
