I've had a hard time "getting" RDF (e.g. how it differs from XML), but this article helps give it context. The semantic web is being built simultaneously from the bottom up and top down. Typifying the bottom-up approach, RDF content is machine-readable at the outset; powerful but complex (with several advantages over microformats), RDF is all about inter-operability. Top-down approaches introduce "metadata sprinkling" to existing content, simple but limiting by comparison e.g. microformats (using CSS class attributes as in hCard), or meta elements (meta tags such as those for geo-discovery). Both approaches are valid, but RDF is hard whereas microformats help "the rest of us" contribute to the semantic web. There may be a collision ahead, however, between microformats and RDFa (sprinklings of RDF embedded in existing XHTML).

WordPress 2.5 lets you search across pages (non-blog entries) as well as posts. This is undoubtedly a good thing, but if your pages are liable to turn up in site searches you might want to make a couple of changes to stop page content from swamping your results screen and improve appearances if you use category icons.

Installation of software you didn't actively choose to install is malware. I'm referring to Apple's recent decision to force Safari 3.1 on hapless Windows users via Software Update. How can you "update" a product that isn't installed? Wife: Have you got anything without Safari? This is bad form Apple. At least Ars consider this browser a much-improved and stable "true competitor".
Microsoft Silverlight is a proprietary cross-browser, almost cross-platform (not yet Linux), and cross-device (WM6 & Symbian only) plug-in vaguely tasked with "delivering the next generation of .NET based media experiences and rich interactive applications for the Web." The developer tools (Windows or Mac) output interactive text, bitmap images, vector graphics, animations, and video (WMV)/ audio (WMA and MP3) playback, in competition primarily with Flash. The plug-in is free (v2 is currently in beta) & curiously you can download the Getting started video in QuickTime for iPod! More here.
iCab—the Internet taxi for your Mac—now sports the Geotag Icon. Alexander Clauss' latest beta (4.0.1b39) enables the status bar Geotag Icon when metadata tags are detected in the page being viewed, generating a pop-up that will plot the geotagged location using Google Maps. iCab has a number of other noteworthy features, including full compatibility with the WYSIWYG editor in WordPress (unlike Safari or Firefox as of this writing). David has some screen captures on his site.
Continuing the recent geo-fixation trend evident on this site, this article shares the results of a slightly deeper delve into GeoRSS and looks at a great browser add-on that offers auto-discovery of geotagged content in webpages and in some feeds.
