My friend had same experience before.

Somehow he thought that he could offer limited information to an online board and get some good advice from some online id's who could be less smart than he.  He ended up following a popular id and wasn't very happy afterwards.

So here is my advice:

1. follow her heart.

2. if she doesn't have a heart, follow a coin.

3. if she can't find a coin, do the opposite of what the online advisers say.
