Please stop using google news. As you can see, it puts in a blank line
between every quoted line, making your posts rapidly unreadable. 
This is excaserbated by your putting a blank line between each overlong
line of your posts (75 character maximum line length would be nice)
meaning that when you quote yourself you get three, then 7 then 15 ...
blank lines between each line of text everytine you quote yourself.
