I love it, but popularity always holds me back. I love the names
Harry,
Oliver,
Jack,
Alfie,
Charlie and
James but they're all way too popular... :(
You also said you "liked" it; don't you mean "love"? Just use names you love, not the ones you "like".
Use it as a middle name if you really love it, or go for a variant, diminutive or a translation:
Olivier,
Olaf,
Ollie,
Alfher,
Aulay etc.
