From what I gather our wordpress.com feeds cannot be substituted by feedburner feeds – So, is it possible to integrate ones delicious postings/feed with ones wordpress.com feed, as you can with feedburner?
you can use feedburner, you just can’t redirect the wordpress feed to feedburner. so you could set up a feedburner feed, and tell all your readers that they should switch their subscription, otherwise they’ll be missing out.
option 2: you can go to del.icio.us, and go to settings > daily blog posting, and ‘add a new thingy’
most of the input fields are self explanatory, except ‘out_url’, which you should set to http://alttablib.wordpress.com/xmlrpc.php.
