I am trying to fill up title and meta description for my [Tumblr](http://www.tumblr.com/) blog.

The way I will do that is via the themes.

For the title, it isn't too much of an issue, I can just get the title for the post although some post types do not have titles.

The **main question is about the description**. I am thinking of **using the start of the body content**. For now, there is no way to limit the length of body content. I wonder **if its OK to have the whole body in the description**?

I have contacted Tumblr support to suggest that they have a way of creating limiting text length in their template tags.
