A few days ago, @florianziegler suggested that all of us running blogs with RSS feeds make a small change:
Please add your email address to your RSS feed.
This email address can be used by RSS feed readers to display an Email button next to each feed entry, so folks can reply to the post via email instead of visiting the post on your site to leave a comment.
That seems like a good idea. I found that there was no WordPress plugin that allowed that out of the box, so I built my own. If you’re a blogger and use WordPress, give it a try!

Next step will be for more feed readers to support that issue. I consequently opened an issue for my feed reader of choice, NetNewsWire, to support this, and another for the Android app I use, FocusReader. If you use a different feed reader, don’t hesitate to contact them about it!
