Hi John,

Penguin is the over-optimization update which is looking for sites that are engaging in tactics purely to rank highly in Google. Google are always looking at ways that they can improve the quality of their search results to keep them ahead of the game and penguin has been designed to look for webspam or those that are overtly SEOing their websites to rank better, tactics include keyword stuffing, link schemes, doorway pages and more. In relation to link profiles they are under more scrutiny than ever and link schemes can be creating link networks to boost your site, using low quality link tactics such as forum and blog comments and having a high concentration of links with exact match anchor text. Also link profiles with lots of links from sites that aren't in their niche as this is clearly unnatural.

SEOs need to concentrate on building quality sites which serve the purpose they are intended for and have excellent usability. Here is Googles take on Penguin in their own words - http://insidesearch.blogspot.co.uk/2012/04/another-step-to-reward-high-quality.html

I hope this helps answer your question - concentrate on building great content with relevant on page optimization clearly using best practice and not keyword stuffing, then make sure you are getting this content exposure using tactics such as social media, but not dodgy tactics to gains links such as forum, blog comments and anywhere else that allows people to create any link for a links sake and you will be fine, in my opinion. A few reciprocal links are fine and natural but don't engage in a practice where you are reciprocal linking to unrelated sites which giving a link to won't enrich the users browsing experience.
