And what does this has to do with anything? Do you have a copy of the Google search engine to run at home? (the real one, not a plain text indexer like Google desktop).
Neither Facebook nor SAP are solving particularly interesting problems. Is it useful to facilitate meaningful human interactions? Yes. Is it valuable to glean insights about the operational structure of a business? Certainly.
Both of these companies do something like this, but emphasizing the wrong aspects of scalability. TechCrunch is still boring, but SAP isn't interesting.
Then you have no perspective of the problems SAP is solving.
SAP is solving tons of big data problems with a variety of interesting data modeling and analysis.
These are wildly interesting problems. They are as interesting in a small startup environment as they are in a large company.
There seems to be this real us versus them attitude with people who identify with startups.
People that work in SAP are no different than startups. Many people that work at SAP come from startups.
It's not a startup versus enterprise thing. It's (partially) a question of whether the interesting propellerhead problems are in aid of an interesting larger goal.
