It has a great business model, with a massive customer base, and by all accounts, it should grow into an absolutely enormous company (if it isn't already).

There are no real competitors to speak of, and the area to grow into is enormous.

As a software engineer, this place has gotten too big for me, and the technology hasn't scaled at all. There's constantly a desperate attempt to manage resources and to make sure no one breaks the site in any way (which is understandable). This means there's way too much process and overhead and not enough time to actually write some code and see how it works. Too many people have conflicting priorities.

My level of frustration at the lack of technology progress is growing. I would leave but for the downturn in the economy. Morale is much lower than I ever remember, and I've been here over 3 years.
