If you guard your time you won't make connections that make your limited time multiply through the help of others. Likewise you can probably do a little for someone that would help them a lot forward.
Don't take meeting when you have work to do. If someone is asking for a meeting so someone can be a witness to their existence, push it to the weekend and take only the most interesting.
If there's something concrete you can fill them in on, or be helped with, be concise, clear and direct about it. There's a lot about startups that you can, and should be learning on your own all the time.
Work meetings can be doubled up during events, lunch, or coffee. Keep it on topic and on time. Getting together after work is an option too, it doesn't interrupt working time.
