From Robin Good's blog, news of two new feed submission tools as well as a manual list to follow in Automatic RSS Submission Tools.
The first is RSS Submit, a $25 product that sends to a variety of feed search engines. The blog post above provides a review of this.
The second is from Thomas Korte, who I've known from his days at Moreover. Thomas moved to Google years ago and also has a personal blog -- hence his interest in feed submission.
His RSS Submission Service is web-based, free, and lets you send your feed out to major indexing tools. Thomas talks about it more here, and he also provides submission tips in Website Promotion with RSS Feeds - four tips.
Back at Robin Good's site, RSSTop55 - Best Blog Directory And RSS Submission Sites gives you a rundown on major feed submission resources along with links. There's more than 55 resources on it now, and you can even take a feed to be notified of new additions and changes.
