I recently made a comment that got a lot of up votes, but I don't seem to have gotten any reputation for it. Is this normal, and if so what's the rationale for this policy?
Any help would be greatly appreciated.
Thank You in Advance.
No. Votes on comments have no influence whatsoever on your reputation.
The rationale is that comments are meant to be temporary, and even highly upvoted comments may be deleted because their purpose has passed. Answering questions in comments is also fairly discouraged, and so there really shouldn't be any reason for a comment to give reputation.
See the MSO FAQ, and this declined feature request.
