Anil Dash is right, and I think I figured out the app that will fill the need.
Based on extensive observation in the nearly 7 years that I've been blogging,  here is how men actually submit comments to a site:
- Skim just enough of the first few sentences so you can get a fair  idea what the topic of a post or news item is.  
- Scroll quickly, as fast as you can! Be careful not to accidentally read any  of the other comments on the page on the way down. (Some of them may contain the  information you're about to post.)  
- Type out whatever opinion you've had on this topic your entire life. Don't  waste time with spelling or punctuation, and be careful not to let any new  information on the page influence your thoughts.  
- Now that you've completed your task, submit your comment and then, at your  leisure, review the other content on the page. If you find that the original  post or any of the comments that preceded yours were written by people who share  your opinion, bask in the confirmation that you were right. 
Now the time has clearly come for modern Web 2.0 applications to reflect this  reality. Where is all the innovation around accommodating this unquenchable  need? We men need to inflict our comments on the web with wanton  disregard for the context, content, and community in which we're participating.  Let's get some Ajax on this motherfucker, stat! 
We need an app that does a live search for articles and comments that match your opinion as you type it. Ideally it would submit your comment to all the sites it finds simultaneously. A filter that just returns comments from the me-too choir would be a nice touch too.
