The most popular SEO plugin for WordPress is certainly the All-In-One SEO Pack. It's on just about every plugin roundup you'll ever see. It's free. It works well. But it's not the only kid on the block. One of the guys from WP Engineer has a competing product: wpSEO. I've now used them both. I thought a head-to-head comparison would be useful for people to see.
“A popular ability in WordPress themes is to add custom CSS driven by options. This brings up a common question, how should the theme inject custom CSS? I’ll outline three different approaches on how to do this.”
A useful tool to have in in your WordPress toolbelt is the ability to quickly and easily search for, find, and replace specific strings of text directly from the MySQL database. We can do this by entering SQL queries either directly or through one of those handy interface applications like phpMyAdmin, which seems like one of the most prevalent PHP applications on servers today.
Turn regular datestamps into more human-readable text (e.g. 22 minutes ago) via a built-in WordPress function.

Still confused about these "custom post types"? We already have categories for Posts and we can use various techniques like post_class to target certain posts with CSS and do different styling. We can also use conditionals to treat posts in different categories completely differently. Why is this going to help?
The big difference is that it actually adds sidebar links to the Admin side specifically for these new types. And beyond that, you can actually declare custom data types for different types. Instead of just "Add Post" and "Add Page", you can have "Add Real Estate Listing", which only will ask for "Property Name", "Description", "Price", and "Sale Status". Powerful stuff!
A while back we talked about upgrading plugins. Specifically the All-in-One SEO pack and the controversy surrounding how it turns it self off after (some) updates. This is what that plugin looks like when it needs an updating:
I just got my hands on issue #199 of .net Mag. I did an article for it on WordPress, and it's on the cover!
They did use the wrong W for the cover, but I'm sure they got enough flack for it they won't mess that up again =). This is probably practically an old issue for UK folks, but big bookstores in the U.S. I find do tend to stock this magazine (Sold as "Practical Web Design" in the U.S.) but always a few issues old, so I bet you could find it around about now.

When designing WordPress themes, I always add a common set of custom functions to the theme’s
functions.php file. This speeds up development time because I don’t have to hunt for and individually copy the same slew of functions for every theme. I just drop in a copy of my functions.php template and build up from there. This takes care of all those little things that always need to be done:
Have a bunch of different areas you wish to declare as a widgetized area? Save repetative code by creating a quick array of their names, then loop through that array calling the register_sidebar() function on each one. Elementary PHP stuff here, but hey, it just saved me quite a few lines of code in a widget-heavy theme I am working on.
Drag to your bookmarks bar, click, get a bunch of buttons for easy access to specific areas of your WordPress admin. No security concerns, other than taking people to your log in page, so assuming you have a good strong password you are fine. Also I suppose this assumes you have WP installed at the root...
WordPress has a bunch of AJAX abilities built in that you can access, without having to use any outside resources. Gary Cao shows how, pointing out good and bad practices.
