Every post that you call get_permalink for is added to the object cache (in memory). Now, if you’re doing a get_permalink call, 9 out of 10 times you’ll need to more of that post than just the permalink, so this isn’t really a problem. However, in some cases, especially when you do large quantities of…
The recent changes from Google and my post about it regarding the highlighting of authors in search caused quite a few questions. People have been asking me how to do specific things and how to make certain elements contain rel=”author” or rel=”me”. Instead of replying to each of those emails and comments I decided to write one…
You might recall that I’ve written a Link Building 101 article not so long ago. Since then, I’ve had quite a few people asking me for link building tips, advice, tricks, etc. I’ll tell you now: I’m not the one to ask. I have ideas about it, of course, but my methods don’t work for…
Recently, while working on the site for my father in law (in Dutch), I wanted to create an XML sitemap for the many publications on his site, that are downloadable PDF’s. I regularly add PDF’s to his site too, and since I’m a tad bit lazy I don’t want to keep updating the XML sitemap. So…

At the end of March Twitter released a cool new feature called “Web Intents”. I didn’t really see the value of it till recently, but I’ve now started using it way more. When you have a Tweet button on your site, you’re already using the Web Intents API, but you can do way more cool…
A while back I outlined my system for preventing comment spam. One of the core fundamentals in there is that I send people an email to verify their email address before their comment is published. For this to work well, I need to trust on my email to be received. As it turns out, email…
Amidst all the news about Google+ and Google social interaction tracking (and yes I will work on & post about that too), Google released some other news today. They said they’re going to be highlighting authors in the search results. I think this is an awesome feature. It means that you’ll see a picture / avatar…
A small note from Joost first: I’m working on a project with Alex Moss from Pleer. He knows an awful lot about the Facebook Open Graph protocol, in fact he did a couple of pretty good plugins for Facebook comments and buttons etc. I asked him to do a guest post about Open Graph here,…
