After searching around for a bit for useful and good plugins, I've found 13 plugins that I find crucial.
And so, here is my list, they are in alphabetical order:

  1. AddThis - Social bookmarking widget: Just scroll to the end of this post to see it in action ;)
  2. Adsense Manager - Put some ads here in the site, even though the revenue never amounts more than a dollar... :(
  3. All in one SEO pack - Generate the necessary meta-tags at the start of every page in your blog, very useful to be a little bit more "Search Engine Friendly"
  4. Code Highlighter - For programming blogs like mine this is a great plugin. Put all your code inside a pre tag, set the language to the corresponding one, and you've got it highlighted!
  5. Download Counter - When you offer stuff to download, like I do in my sample pages and stuff, it is always nice to have a counter of how many people actually download your stuff :)
  6. FeedBurner FeedSmith - Redirect your feeds to a feedburner feed, a very interesting option that allows you to use the feedburner feedstats!
  7. Google Analyticator - Insert your Analytics tracking code in your blog, to be able to access google's most powerful stats tool.
  8. Google XML Sitemaps - Automatically create sitemaps and notify several search engines with this great plugin
  9. Role Manager - Easily manage user roles and privileges with this amazing plugin. Great for blogs with multiple contributors, editors or admins.
  10. StatPress - One of the nicest blog stats tool, similar to google's analytics, but I prefer to have both, as each offers different information.
  11. Subscribe to comments - Give your visitors the ability to receive emails upon follow-up comments.
  12. wp-Cache - Easy caching for your blog, makes loading time faster, and reduces significantly your mysql queries.
  13. Typogrify - Correct some "aesthetic" issues regarding text, like thin spaces, widows, quotes and much more.

And of course the built-in great Akismet spam filter, which works astoundingly great, and some other "minor plugins" that I don't consider to be enough important to be here...
If you liked this list and you are a stumbler please consider thumbing me up ;) Thanks for your support!
