Weblogs are densely interlinked.
This anchors blogs in the public arena, as part of a communal discourse.

Posts to a blog can be very short and unpretentious.
The threshold for publishing a single post is very low.
This allows single, small, insignificant ideas to be expressed and formulated.
Sometimes these thoughts are left as they are.
A paragraph is enough and there is no more needed.

Other times, the ideas grow.
Someone links their site to the first post, comments on it, and a conversation grows forth.
The initial post, or follow-ups are linked to a web site or a newspaper article or something else.

Links are like roots, tendrils, reaching out between fragments, creating a context for bits and pieces that at first glance may seem to be unconnected fragments.
