Ego

Ego gives you one central-and lovely-location to check Web statistics that matter to you. With support for Feedburner, Google Analytics, Mint, Squarespace and Twitter, you can quickly view the number of visits to your website (including daily, hourly and monthly numbers), feed subscription totals and changes, and how many people are following you on Twitter.

No more visiting a bunch of websites, logging in and out, all that nonsense. Ego supports as many widgets of each type as you want, so you can check all your stuff in one go.
