I copy pasted the below email that came to me from Yahoo Search Marketing. Call it a free yahoo overture ad but the word optimized PPC giving special attention to first 70 characters might be a hint to all of you or simply a waste of forum space but when they are talking about auto optimization and other stuff, I just want to see how they do

A new look is coming to the Yahoo! search results pages that
will translate into more clicks for your listings. On January
18th, Yahoo! will debut a streamlined design that will make
the search results displayed on Yahoo! even easier for
consumers to read. Our research has shown that by improving
the search experience in this way, advertisers can generally
expect to see an increase in clicks, while maintaining their
conversion rates.

How this change impacts your listings:

* Yahoo! will display shorter descriptions for Sponsored
Search listings
* You don't have to make any changes to your listings; they'll
be automatically shortened for you when displayed on Yahoo!
* If you'd like to optimize your listings for Yahoo!, begin
your description with one short sentence that includes your
keyword and focuses on your most important information in
the first 70 characters
* Over time, we will fine tune the exact character count that
we believe works best for advertisers and search users
* Most of our partners, including MSN, CNN, ESPN and Infospace,
will still display longer descriptions for your Sponsored
Search listings, though the exact length may vary from
partner to partner

Yahoo! is taking this step to improve the search experience
for its users. By continuously focusing on delivering highly
relevant search results in a user-friendly format, Yahoo!
also gives you the best possible platform for reaching customers
interested in what your business provides.

Sincerely,

Your Partners at Yahoo! Search Marketing
