Even when the IPO market seized up for a few months in August, venture capital and private equity money continued to flow. And with companies continuing to file S-1s, we remained fixated on who would have the biggest exits. When you see our top deal stories this year, Zynga obviously played a major role in our readers’ interest, especially given the shareholder structure and corporate governance issues that arose en route to its IPO.

Let’s take a look at the top five deal stories from Inside IPO this year:

1. Jive Software IPO: here’s who gets richest [CHART]If Jive Software goes public at the expected valuation of $1 bn, a considerable amount of wealth will be created.

5. Zynga’s dangerous new gameWord of Mark Pincus’ plans for a third class of shares for social gaming company Zynga spread like wildfire across the internet yesterday. The CEO is looking for 70 times the voting rights of ordinary shareholders, and he’s already secured approval by Zynga’s board of directors.
