For some projects, it's nice to output clean, well-formatted markup. Using theme template files enables great control over most of your (X)HTML formatting, but not so much for automated functionality involving stuff like widgets and custom menus. One of my current projects requires clean, semantic HTML markup for all web pages, but also takes advantage of WordPress' custom-menu functionality to make things easy. In this DiW article, we'll see how to enjoy both: WordPress custom menus and clean, well-formatted HTML markup.
One of my clients was hacked with the so-called "Cannot redeclare" hack. It seems closely related to the nefarious TimThumb hack, so if you've been hit by either of these hacks, you should check for the other. Apparently these hacks affect shared servers, so if you host multiple WordPress sites, chances are high that they're all infected.
Everyone loves a good comment. Readers benefit from the shared information and authors appreciate the conversation and feedback. But you gotta keep the spam out. Akismet and other anti-spam plugins do an excellent job of automating the process, but it's a good idea to watch out for false positives: legitimate comments marked as spam. Rescuing ham comments from the spam pile promotes healthy comment threads and improves the quality and reputation of your site. In this DiW post, we explain how WordPress & Akismet deal with spam, discuss anti-spam strategy, and share some ham-saving tips and tricks.
Recently I worked on a project where a single RSS feed was imported and displayed in multiple columns on the web page. Certain pages display feed items in two columns, others in groups of three or more. This technique uses WordPress' built-in
fetch_feed functionality to parse external feeds, and a slice of PHP magic to display them in multiple columns. It's flexible too, enabling any number of columns and feed items from anywhere in your theme/template files. For example, you could display any of the following:
We get quite a few requests for 1-to-1 WordPress support, but unfortunately don't have the resources to help everyone directly. We frequently see emails like this:

WordPress does an excellent job of keeping track of what's happening with the loop, but once you start customizing parameters and setting up multiple loops, it's a good idea to explicitly reset them using one of three WordPress template tags. In this DiW post, we'll explore these techniques to get a better understanding of when and how to use them in your WordPress themes.
WordPress makes it easy to publish content in any number of categories, with any number of tags, and with any type of custom post format. So for example, in addition to full articles, you could also offer screencasts, links, side posts, tweets, and all sorts of other peripheral content. Complementary material may work great for visitors surfing around your site, but including all of that extra stuff in your RSS feed dilutes the potency of your main articles. The idea here is that your visitors will subscribe to the more focused content.
Nice little infographic showing the usage of WordPress among the worlds top 100,000 sites. Amazing to see that people out there are still running WordPress as old as version 1.5!
