I've been in one myself, but it didn't last (my fault though).
I'd say they can work, but if you're never going to see that person in your life, then I think perhaps not. To have a proper relationship of any kind, I really think you need to be able to spend some time with that person, as well. Skype is nice and such, but it's still not the same wonderful feeling of actually physically hugging someone and such.
I recently had an internet crush myself, which probably makes me sound slightly scary... But yeah, you meet some really nice people on the internet and ones that share similar tastes to you (as you said). So when you start talking to someone like I did and find out how wonderful they are, it just amazes me so much and kind of wish I could have a relationship with a person like that. I sound incredibly sad... I know, but yeah I do lack that part in my life.
That said, I am shy and lack confidence and the internet is way more easier to communicate with people than actually in person.
I think it's something you'd really need to think about and make sure it could really work and that you'd get to see this person. If you can live without any physical contact with a person, then maybe it could work, I guess it'd just be a different way of having a relationship.
Either way, good luck if you do go into one. You've always came across as a pleasant guy to me Josh.
