Have edited again the daily blog posting of del.icio.us, have to wait to see if that works again.
Found a few mistakes at subscription links, amended them and hope that it's now working for those who wants to subscribe via feeds.
Added del.icio.us link rolls to the sidebar at the bottom. Strangely it doesn't wrap I'll have to find out why and fix that. There are many plugins to integrate del.icio.us with WordPress, may be I'll look for one I like later.
