FHDC now has a diary reader that can read Diaryland, LiveJournal, and any other RSS news source. Click for more info.The FHDC diary reader aggregates updates from different diary and news sources and prints the updates on the main page. This is the first software I know of which is able to do this (since neither Diaryland nor LiveJournal offers RSS feeds). It works for most diaries, except heavily customized Diaryland tempates which override the date formatting on the older.html page. If you come across a diary that doesn't work, just ping me and I'll add the capability to scrape it.
As always, this is beta software and please let me know if you have any ideas or bugs to report. Thanks!
