Ye' old general discussion board. Basically, for everything that isn't covered elsewhere. Come here to shoot the breeze, shoot your mouth off, or whatever suits your fancy. This forum is not for asking programming related questions.
I just added this extension to my browser and it is quite cool, shows HTML errors and warnings for each web page you visit as a neat little message in the status bar. Unobtrusive, and quite interesting. The home page of this site has 48 warnings!
But that's nothing -- weather.com has something like 69 errors and 956 warnings on one page!
I'm actually using it to make sure the sites I manage are okay, and I like the unobtrusiveness yet ready availability of it. You can right-click on the statusbar message and select "view source" and it will list all of the errors and warnings as well as show the source with the e/w's highlighted.
It's also neat to see how sloppy some commercial sites are, though.
Hmm... I think I want this extension! I'm currently using Web Developer Tools FireFox Extension to validate HTML, but all it does is make it really easy to send HTML to other sites that do the work for you.
Hmm... you're right! This site doesn't validate! Looks like there's a mix of XHTML and HTML in here (I think I saw a few <br />s in the code, but this is HTML 4.01 we're talking about!)
