I'm surprised no-one else here has mentioned this ... maybe they want to keep it top secret ... if so, I could be in trouble here !
The ODP people are "tentatively" planning a major reorganisation of the ODP to improve listings and search results. They have cited [uk.yahoo.com...] as an example of how Dmoz results might appear.
The reorganisation involves editors having to flag the country for the website. It won't matter what TLD is used, so long as the editor selects the correct country code, the site should show up in country specific search results.
The implementation of the flagging of sites is to be phased in gradually, with the UK being the first due to the large number of English sites and editors. All .uk domains should have been automatically flagged, with editors having to manually flag other UK based TLDs.
Potential uses might include geographic search, and might also include geographic sort of general results (maybe similar to Googles sort by page rank or sort alphabetically). Huge possibilities!
This can also cure the problem of getting sites listed in both general (top level) and Regional categories. The potential will be there to remove the Regional categories at some point in the future (apparently not decided on yet). I'm sure you can all think of many other uses for this flagging!!
Of course, this can improve the value of the ODP for other organisations using ODP data such as Google. If the reorganisation goes ahead soon, the ODP could be far more valuable to major search engines than Looksmart etc. Could this be the beginning of the end for Looksmart and other paid inclusion directories ?
That's all I'm going to give away on this as details are fairly sketchy at the moment. All ODP editors should read the thread in the Open Directory Editor Forums (General forum)
