Hm interesting thought. Any good tutorials/sites I can use to get going on this? Or is it so simple I won't even need that. I find myself scraping a lot, so finding the best lib for that is a priority.
That's the key advantage as I see it. If I'm scraping something it's often in a hurry and I just want it done. Not having to internalise a new API is a significant win in that respect.
