Can someone tell me how and why I lost my PR 3 to PR 1?

I entered your url into majesticseo and the backlink tool there says you had no backlinks before June of last year, and today you have almost 4,000. What does your link profile look like? Do you have a good distribution of social, themed, and no-follow (all of which is what 'normal' looks like) or do you have a bunch of low quality backlinks that were penalized in the recent Google changes?

PageRank is simple to understand. Your PR went to 1 because either:

1. The highest pagerank of the linking page is now 2 instead of 4 what it used to be
2. The highest pagerank of the linking page is higher than 2 but with excessive outgoing links splitting up PR too thin
3. PR4 or higher link you had is gone or nofollowed
4. You were selling links and got a filter reduction of pagerank to make it less atractive for purchase (unlikely as your PR is low anyway to start with).
5. The highest pagerank page on your site is now a sub page (did you check?)

That's all I can think of for now...
