I respect Groupon. They've built a good company predicated on a good business model in record time. They properly deserve all the fortune they reap.

That said, I don't understand why they are seen to be a technology company. They are basically a massive sales organization. I'm sure they use technology to tie together their sales automation, but I doubt it's anything more significant than any other IT installation at any other medium-sized sales-oriented company.

Perhaps I'm missing something. Why is Groupon hailed as a technological marvel?
