In the past I have put together a list of my favorite WordPress plugins that will help extend your blog’s functionality, search engine optimize it and so forth. In addition, there are a number of tools that are not plugins that you could add to the blog or incorporate into your blog. Here is my list of favorites (in no particular order): 

• Feedburner – track readership of your RSS feeds
• Flickr – a tool for moblogging; it provides a gateway to post your cameraphone photos directly onto your blog just by emailing them as attachments
• Swicki – add web search and a “what’s hot” buzzcloud to your blog
• NetNewsWire – awesome RSS newsreader for the Mac
• coComment – track your conversations on others’ blogs
• TalkDigger – monitor discussions that reference your URLs
• Google Analytics – free, hosted web stats service (from Google’s Urchin acquisition)
• del.icio.us – add favorite sites to this social bookmarks site using the bookmarklet provided, then display your favorite links on your blog’s sidebar with a del.icio.us plugin
• FeedBlitz – so your blog readers can subscribe to an email newsletter version of your blog
• Ecto or Qumana – draft blog posts while offline
• Technorati – “claim” your blog and create a profile to improve your visibility in this blog search engine
• Pheedo and BlogAds and AdSense – make money with your blog from advertisers
