Are 60 outgoing links to another Web page too many?
No, as Google is only concerned with pages of over 100 outgoing links. Google considers overly linked pages to be link farms, and they are penalized as such. Your site will not a experience a problem, although each page linked to your page will receive only very small amounts of PR flow. PageRank can decrease if you lose some important links that are no longer linking to your site. PR loss can also occur if some of your linking partners also experience a drop in their own PR, possibly setting off a chain reaction of lower PageRank all through the immediate linking network.
