Difference between WordPress and Tumblr?

The very first difference, is that tumblr is basicly an extended micro-blogging site, wordpress is a full featured blog and website.

For example, wordpress can be used as a portfolio page side-by-side with a blog and a news site and something else. Of course, you’re talking about wordpress.com, which has limitied capabilities compared to a standalon wordpress install.

Tumblr on the other side is an extended micro-blogging site, like Twitter, just you can add longer, lot longer postst, with pictures, videos, and so on.

For someone, who wants to create a blog (web-log, as web diary), both have the same possbilities, but if you want something, what can be extended, that’s gonna be wordpress.

This is my opinion, of course.
