I think online relationships can work, but it depends on the individuals involved and the circumstances around it.  The thing to remember is: everyone is different, each couple is different, and every circumstance is different.  For someone it might be the right choice to hook up with someone they met online after a few months of knowing the person, but for someone else it might not be a good idea to get into a relationship with someone they've known online and had a crush on for years.  In the end, it's a risk that is up to each person to choose whether or not to take.  Even if it is against their better judgement.
Of course, in order for it to work out, the couple has to meet irl at some point.  They can't be in a relationship and never physically be in the same place.  It just wouldn't work.
