1 - Networking: 

Developing a network of peers working in the same technology area is vital. Discussing your current project and bouncing ideas off of people who might have a different viewpoint can give you a fresh perspective, and encouragement to keep going when you hit a roadblock. In addition, there are long term benefits, too. As many as 60% of tech jobs aren't advertised formally. It's likely that your perfect job opportunity will come via your network. A recommendation from a peer carries a lot more weight than passing your resumé across someone's desk. Then there's the social aspect: exposure to other cultures, discussions about other markets and economies, forging friendships over cocktails, bonding over your favourite song during Karaoke. There's no end to the possibilities! 

2 - Learning opportunities: 

Solving business problems through shared experiences - If you're facing a problem, chances are that someone in the community has already faced and solved that very problem, and can help you with advice or guidance. If you're looking for a better way to do something, hearing how others implement solutions can help you think outside of the box. Speakers at user groups are generally considered experts in their field, and therefore have a wealth of knowledge, and are always willing to share. Attending sessions gives you the opportunity to ask questions, and perhaps even stick around after the session for a more in-depth discussion with the expert.  Customer presentations are the heart of user groups. Explore new solutions, hear frontline stories, get valuable ideas to optimize your productivity.
