mail filters?
First of all, I take umbrage at Yahoo's suggestion that the browser I choose to use is not the most current available for my operating system.
Because I choose Open Source software over corporately owned software, you are making a conscious decision to deny me the benefits of your 'new and improved' Yahoo email web UI. On what basis to you take it upon yourselves to tell ANYBODY what software they shall or shall not use? That is the height of hubris by any reasonable person's standards.
On the slim chance that an honest-to-God human being reads this, I challenge you to justify why Chrome should work with your oh-so-shiny-and-new web interface, but it's Open Source brother, Chromium should not? I don't believe it can be done except for the old and tired 'because I say so' gambit. I find it quite humorous that the industry leaders in free email have NO technical issues with Chromium. If I were Yahoo, I would be ashamed and embarrassed.
So when you are all done stepping on your johnsons, would you also like to explain and justify why every other email provider known to the Internet offers email filters and Yahoo doesn't?
Some day I really want to meet the chimpanzees that run your mail service!
