Wordpress plugins you MUST have

My tiny blogger experience (I’ve installed, configured and maintained more than 7 wordpress blogs, about 5 Blogspot ones and one Textpattern) made installing the must-have Wordpress plugins for this new blog a breeze. This comes mostly from having made myself a list of the MUST-have plugins. Vital for some, nice-to-have for most, they can make the difference between a popular blog and an anonymous one.
There are many great Wordpress plugins out there, but this is the list of the ones I installed right now. Surely you must have extra suggestions, which are welcome in your comments.

• Akismet comes by default with Wordpress but still has to be enabled. It is THE TOOL for comment spam protection (remember that this was one of the reasons I dislike Textpattern?
• All in One SEO Pack - should optimize the page for extra search-engine love. I’m taking a shot in the dark with this one, since it’s the 1st time I use it. Still, looks promising - no need for setup, just activate it and you’re set.
• Google Sitemaps This generator will create a Google compliant sitemap of your WordPress blog. - also for greater Google search love
• Permalink Redirect This plugin ensures that pages and entries are always accessed via the permalink. Otherwise, a 301 redirect will be issued. - same Google search love. Also, it’s great if you want to redirect all your rss readers to a Feedburner blog - it’s automatic and hassle free.
• wp-cache Very fast cache module. It’s composed of several modules, this plugin can configure and manage the whole system. Once enabled, go to “Options” and select “WP-Cache”. - I never seem to get this straight. Gives me a bit of headaches to make it happen; but once it’s on, the Digg effect (the joy and nightmare of any blogger) becomes a pleasant breeze; shortly, this plugin makes your wordpress site resist to hundreds of simultaneous visitors, even on shared webhosts (such as Dreamhost).
• WP-PostViews Enables you to display how many times a post had been viewed. It will not count registered member views, but that can be changed easily. - a nifty toy that’s great for discovering and making public your most popular articles.
• WP-UserOnline Enable you to display how many users are online on your Wordpress blog with detailed statistics of where they are and who there are(Members/Guests/Search Bots). - want to see how many people are watching your site right now? Then this is the way to go!
• Ultimate Tag Warrior - the most popular tagging plugin, makes tags (lightweight categories) for Technorati friendliness. Also pretty SEO friendly, so it’s always good to have around.
