On his blog, Doug Belshaw wrote about the 1024b Club, a directory of websites that are less than 1024 bytes.
The requirements of 1024b.club are quite… stringent, shall we say. 1024 bytes is a single kilobyte. For those reading this who may be 'less technical', do you remember 3.5″ floppy disks? They stored 1.44 megabytes of information, which means (if my maths is correct) you could fit 1474 of these tiny websites on one of those disks. Wowzers.
