Web 2.0 expandable sections
I like Google Mail and all that fun stuff but a lot of things about the "next version" of the web are just annoying. One of the things I find most annoying are the "expandable sections"; where you have to click the little plus sign next to or directly on a link to expand and make visible a block of text and/or images. Nowhere is this more annoying than in "frequently asked questions" and technical support pages. I swear if I have to click on another "do you support this feature?" link just to see a "no" open up underneath it I will scream.
Portals just to have portals
A government agency recently changed their perfectly working set of static HTML pages into a hideous, moderately functional, PHP driven "portal" (and yes it has a thing to click on to hide the portal, see above, grrr). Why? Now all of our bookmarks to key pages do not work. Why spent a crap-load of development time on static content? The content of some pages hasn't changed in nine years! The "portal" offers virtually no functionality beyond what was there before.
