In general, it's better to set your posts to ping automatically on posting - your blog software probably comes preset with pingomatic or other ping update sites.
Not sure what the problem was with Digg. If you are logged in you can submit a URL, and then it should bring up a form page where you can supply a description, category, etc. and complete a CAPTCHA verification. It may also suggest other articles that look like duplicates, which you can safely ignore if you wrote the new content yourself and nobody has dugg it yet.
