Or if you prefer things the way they are, vote this up.

exploiting the top comment :)

my only request is that my comments that received reply could have a different color so that i know they were replied because I missed reading replies on time.

And vote THIS up if you want there to be user-configurable values via SQL injection exploits:

http://news.ycombinator.com/x?fnid="begin;update Skins set Font='Comic Sans' where userName='mynameishere';commit;"

SQL injection? You'd need something more like alist injection.

or if titles should be bigger w/less contrast. I like .title 11pt or 12pt and a:link less than black, maybe #222222 or so.

'... fonts bigger ...'

In Fox, "Ctrl +' for bigger and 'Ctrl -' for smaller

'... and visited links darker ...'

good point in Fox de-select, "Edit-Firefox preferences-Content-Colors-Allow pages to choose their own colors, instead of my selections" will change the link colours but also the background.
