Because people won't use titles that let you figure out if you want to follow the link without making the server send the page to everyone so they can read it to find out if it's even intersting to them ...
sorry - curmudgeon mode this morning.... after reading four posts in a row that gave me no clue what they were about until i got to the site and opened the page.
PLEASE PUT A MEANINGFUL TITLE ON YOUR POST!
thank you.
rant off.
