This is going to sound stupid but you should pick up as many as are useful to your specific needs. If you are super desperate for money, you might end up with a ton of angels. (Just remember the tradeoff that you will be managing a ton of personalities forever.)

On the flipside, if you can find a small handful of angels that not only bring money but who can help you with sales, marketing, or operational, then go for it.

Never forget the time commitment that you have to put in to every single person who gives you a dollar.
