Code for a one-click subscription link to Google Reader. I'm thinking about whether the subscription could be exported to the personalised Google Homepage. Maybe I'll e-mail Google & ask them.
Here's the location for the sub link to Reader, anyway:
http://www.google.com/reader/preview/*/feed/http://your feed here.com/
Insert your feed address in the URL, place the link on your site, & press "subscribe" on the Google Reader page once you're viewing the preview. Button highlighted in the image because it didn't really leap off the page & grab me.....
Many thanks once again to Fritz at Cyclelicious for the link code & the screencap. Much appreciated. I'll check out ways to export this to the personalised page, & we'll see if we can't hook Jason Calacanis up!!
Update 10/11: I suggested in the comments that you had to add stuff one source at a time. That may have been true when I looked, or I may not have been paying attention.... I certainly didn't go back to correct myself. Let's do that: I was able to import all my kinja subscriptions using OPML, all at one time. Check out my newer post about reader.
