In WordPress specific forums or in any blog WordPress permalink
structure is big issue. In the process of MYOwnWordpress:) I had the
permalink structure to /%year%/%month%/%date%/%postname%. But after
seven days or I changed that to /%category%/%postname%/.

The reason was really logical First: I  used to daily posting because
there was hardly any use of posting tons when there is no one to read
them.

Second: I liked the inclusion of the category slug because it provides
another keyword including the post slug. I used to the Dean’s
permalink migration plugin to setup a 301 redirect from the old
permalink structure to the new one.I am able on the verge of launching
to the  another blog.while setting up the blog I putted into a fix
through this permalink structure thing.
