Dmoz doesn't seem to be adding sites much in the last few months.
Depends on the area. It had been very difficult for editors even to log in for several months due to the load on the server. Currently the back-end dmoz.org systems are undergoing a massive expansion, and the editing side will be entirely unavailable until at least Monday, Pacific Time.
Most categories indicated they haven't been updated since mid spring or earlier.
What do you mean by most, and what do you mean by categories?
- Suppose a listing were added to Widgets/Blue on March 1 and another to Widgets/Blue/Spinning on March 10. Since the listings in Widgets/Blue haven't changed, it will still say the category was last updated March 1, even though there were more recent changes to its subcategories.
Moreover, the static pages on dmoz.org do not reflect the state of the database before it was taken offline, but are a snapshot taken from a backup made in June.
submitted them to the right categories once a month
If I recall correctly, new submissions overwrite old ones.
I don't understand how dmoz could be petering out with all of its volunteer help
Even though ODP has scaled much further than Yahoo managed, it is still seriously understaffed by almost every measure-- in proportion of the web to be catalogued, in proportion to the number of sites submitted by webmasters, in proportion to required maintenance on existing categories, and so on. There is a high rate of burnout, particularly in commercial categories but also other areas which receive large volumes of marginal quality submissions such as fan sites or personal home pages.
In comparison with fixing bugs with the internal systems and getting the editing forums online, it's quite a low priority. Autumn, the head of the technical side of DMOZ, was still at work after midnight last night ensuring the forum data transfers were successful.
