Since I seem to be in the mode of blog traffic exchange annoyances, here's another current peeve: Blogs that are configured only to work with one browser or another. As a specific example: blogs that are configured only to work with Firefox.
While I don't mind (heck, I encourage it) competition for Microsoft's Internet Exploder, I mean Explorer, browser, I also recognize that a vast number of people use the browser that comes with their operating system. If I create a web page, I want to know that it displays correctly for, and works correctly for users of any browser that might visit the site.
Creating pages that make use of features that are non-standard is stupid and arrogant. There are standards that should be followed, and while it may mean pages are more simplistic and less feature rich for everyone, there's absolutely no reason to force the rest of the world to bend to using your favorite browser.
The same can be said of Microsoft's own Internet Explorer as a preference. Again, there's no reason to use special coding that looks great in IE, but won't render at all, or doesn't render correctly, for a user that happens to be using Firefox, Netscape, Safari, Opera or any of the other browsers that are out there.
I'm not suggesting that you should horribly dumb down your web pages and blogs, but please be considerate of the users of the traffic exchanges you are members of. If you want to avoid having visitors simply click past ("surfing too fast") your site, then use templates that are friendly to the largest numbers of browsers and users.
