Capital letter typing in title surely is not shouting, it's advertising.

[past-times]

Why is advice found on not typing your item title in capital letters. It should be bold and easy to read and capitals increase the font size

for a one line read.

It's just a title , i don't find that a seller is shouting at me in a title on an item , if it was a conversation such as an email etc then yes it would have that impact. I have my titles mainly in capitals , instead of insipid small letters! Whats your thoughts out there on it being in a title ? Do we really care , would you not click on the item because of the capitals?

I tend to do what Cats said, have the keywords in capitals, like a brand name/type. The remaining words I use a capital for the first letter of the word, except words like the or of. I wouldn't put the whole title in capitals. It looks tacky and unprofessional to me (my opinion only!)

A little off topic but may be relevant to some.  Don't use Capitals in URLs on your website.  If your server is Windows based it's not an issue Windows is case insensitive, however, if your server is Linux based uppercase and lowercase addresses are seen as different addresses.  So if your address is uppercase a user entering it as lowercase will get a dead page error.

Makes sense. Unix presumably uses pure ASCII codes, rather than forcing everything to lower case. Something we can all thank MS for. 

After all it is pretty complicated to deduct 64 from any ASCII character greater than 63 in order to force lowercase.

Sort of.

Windows Unicode is UTF-16LE, and each character is 2 or 4 bytes. Linux uses UTF-8, and each character is between 1 and 4 bytes (ASCII Compatible).

The reason for the difference is probably historical as the earliest web servers were mainframe running UNIX and case sensitive file systems, and then along comes PCs with simple OS and servers such as Windows IIS with their case-insensitive file systems.
