Just let me add my 2 cents...
When I looked at the screenshot with the link examples it wasn't clear to me at first glance what was the link and what is just text. Maybe that's just due to my monitor (including settings of color, brightness and contrast). Or because the screenshot contains a lot of different information in a comparatively small area. So I'd prefer links a little bit more "screeching". Maybe more like the yellow ones of the wrong links section.
In the other screenshot of the latest posts list the links are easier to recognise. I guess that's due to the different background and of course the bold font.
I played a little bit with kaputtnik's color suggestion. My suggestion would be rgba(254, 234, 138, 1) for normal links.
Concerning the heading links I just want to remark that it maybe doesn't look good if you have several sections with headings, some of them are links and some not. At least if heading links are of different color than normal headings. But I understand that links need to be identifiable.
Anyway, thanks for your effort to improve the website.
