MailChimp recently had their logo revised. At first glance it is basically the same, but upon closer inspection the logo is changed in many places to enhance readability and for a better overall flow with the letters. The tail of the “p” is a conspicuous example of the efforts to enhance the readability.

This is a great example of subtle type centered changes making the logo more pleasing to the eye, and all importantly; readable across the size spectrum. When a logo is printed at a small size, like on a business card, the ink runs ever so slightly and too tight a space can close during physical reproduction. A good logo design company will take care of these issues from the start, anticipating all the nuances of production.
