Come one old fogeys, age is not an excuse. A bit overwhelmed by the amount, and also lack of variety? I would concur. That's why there are sites out there, like www.animenewsnetwork.com, that help you to a better extent. At the moment I get my fix via sites that have scanlations (scanned and translated manga chapters), but it's a great way to get to know about a bunch of great manga out there, and it helps me narrow down which ones I will eventually buy once they are available in North America.
