Tumblr pros and cons

Still wondering if Tumblr is for you? Mashable has a great post listing the pros and cons of this social networking/blogging system:

Pros:

1. It’s User-Friendly.
2. It’s More Social.
3. It’s Categorized.

Cons:

1. There’s a Lack of Analytics.
2. It’s Unreliable.
3. There’s a Lack of Native Comment Functionality. 

I like Tumblr, but I’d recommend using is as one more tool in an overall online communications plan.
