Some websites I have found interesting (in no particular order):
When Can I use… — Pretty awesome website with information on when cool HTML 5 features will be implemented in browsers.
Mandatory alt attribute is insignificant — Why are we discussing this still? It shouldn’t be mandatory because a site’s users aren’t necessarily going to write alt text. Flickr should be able to be complient even if I am lazy. End of discussion.
The Real Cost of Microformats — A pretty convincing argument against microformats.
Where data goes when it dies — And the flip side, after Ma.gnolia’s recent data loss, people were able to reclaim their bookmarks through the Google cache and microformats.
Pipe Viewer — Cool command line utility. Not sure when I’d need it though…
