It is up to the individual, but please make it an informed choice.
Again, I say, read the link. It won't take the 30 minutes that watching the video will, and it should arm you enough to fully consider things before committing to any action.

Here is a good quote from there:
"Military intervention may or may not be the right idea, but people supporting KONY 2012 probably don’t realize they’re supporting the Ugandan military who are themselves raping and looting away. If people know this and still support Invisible Children because they feel it’s the best solution based on their knowledge and research, I have no issue with that. But I don’t think most people are in that position, and that’s a problem.
Is awareness good? Yes. But these problems are highly complex, not one-dimensional and, frankly, aren’t of the nature that can be solved by postering, film-making and changing your Facebook profile picture, as hard as that is to swallow. Giving your money and public support to Invisible Children so they can spend it on supporting ill-advised violent intervention and movie #12 isn’t helping. Do I have a better answer? No, I don’t, but that doesn’t mean that you should support KONY 2012 just because it’s something. Something isn’t always better than nothing. Sometimes it’s worse.
If you want to write to your Member of Parliament or your Senator or the President or the Prime Minister, by all means, go ahead. If you want to post about Joseph Kony’s crimes on Facebook, go ahead. But let’s keep it about Joseph Kony, not KONY 2012."
