The primary link to be used in external references to this post, its permalink, began as http://www.ideaxchg.com/?p=166, using WordPress’ default permalink format. It would be friendlier to users and search engines to provide a more meaningful format of permalink URLs.
To change from WordPress’ default numeric style of permalinks, use the Settings, Permalinks command in the Dashboard. I’m selecting the simple “Post name” format, without any date portion. Since each post begins with a line that includes the posting date, that will suffice for my purposes, and I’d prefer to keep permalinks short. (The equivalent custom structure permalink specification for this is /%postname%/.)
