Keep in mind that every alternative free library to do something adds cost to the task of selecting a library. Some open source projects (not suggesting any specifically) actually do make life worse for people because they spend time studying it only to find it's not useful.

In my book, spending the time to see whether something is useful (or works) or not, is called "due diligence".

I'm also of the opinion that the time spent raking through libraries that look useful to you to find out if they really are useful to you, more than offsets time you'll spend looking for bugs in your program which were caused by using something which turned out to not do what you thought it did.
