"Only assholes get patents"... Everyone would get and enforce patents if it weren't so hard and expensive to obtain them... I think saying don't get software patents is terrible advice...

Of course, don't go and patent a mediocre interaction or technique, but definitely, pursue a patent if you have worked hard on researching and developing something that is key to your business and that could be used by a better established and wealthier competitor to take a market advantage.
