Yeah. I was only referring to scaling in the sense that the number of users increases. Often, it is easier to implement an application by ignoring scalability, and you can get it out the door quicker.

However, this can be a terrible mistake if your users are not resilient to downtime or lost data (e.g. in the case of Facebook games). Even just a few hours of downtime or slowdown can cause a significant, permanent drop in users.
