Your oldest blog entries will naturally settle to the bottom of the list. You may configure 1, 2 or 3 columns, and either down-across, or across-down distribution of entries or articles where multiple columns are used. Older entries can become links at the bottom of the page, and the oldest entries can migrate into archival access.
Any entry may be unpublished manually or automatically if the content is no longer applicable to your website. Older entries can also be edited if the content requires changing.
