I think an easier and a lot of additional features in facebook, because facebook can post the article to the many letters, how about you?
Well, this question is easy to answere. Obviously Twitter is a lot easier to use cause it has way less features than Facebook, plus they're different websites with pretty much different purposes. Facebook is much more complex.
Both are easy to use for personal as well business. You just need to learn tactics how both of them can be benefical to you.
Both are fairly easy to use and both have their own pros and cons that are rather independent of each other.
i think the question is quite ambiguous, because it is quite hard to compare both of them, whereas facebook and twitter provides different features. Facebook offers much more features than twitter, because in twitter you can only update status ( similar to facebook update status) Well, at least, that is my opinion
To which you are more familiar can be more easy to use. For a newbie Twitter can be more easy comparatively.
Both are ease to use. But surely Facebook has more features and also shows a way to developers to create different apps for websites & Facebook.
