It would be good to have a link to open feeds in NewsBlur and possibly subscribe to them. Something like:
http://newsblur.com/try/http://blog.newsblur.com/rss
This will allow people to teach their browsers about NewsBlur and more easily subscribe to feeds through there.
When visiting a feed in Firefox it will show subscribe options on top. You can change or add feed readers there, through about:config, by adding a URL where %s will be exchanged for the feed URL.
Through extensions Google Chrome can easily be made to support RSS feeds and a Firefox like subscribing option. I use Google’s RSS Subscription Extension for this. Here too a URL with the %s substitute van be used.
http://newsblur.com/try/%s
In my mind, this should give a view like the try options on the NewsBlur dashboard. This way people have an easy way to check out the feed and subscribe to it.
http://newsblur.com/add/%s
Might be added, to give people the ability to skip the try view.
With URLs like this available people could easily make bookmarklets as well, making NewsBlur much more accessible from anywhere in the browser.
