Ahhh, the good old days...when you could publish a post and it would pop up on everyone's Google Reader, since almost all of your followers were from GFC! Things have changed. I really want to know about your new posts, and I'll bet others do too! Here are some things I always do to make my followers aware of my new posts...
Facebook: I go to my blog FB page and post the link. A while back Google stopped posting regular feeds I'd set up from my blog, so this is a manual process that I do each time I post.
Google Plus: Not sure how well this picks up posts, but I always update with the link there too.
Google Reader: Supposedly, Google Reader only posts your latest post if someone manually refreshes your feed. I don't know - sometimes it's there right after I publish, sometimes not. No matter, if I can't find it on my reader, I find my blog and refresh it.
Linky Friends: LF's blog reader directs followers to your main blog page, and lists the latest post as whatever you manually entered. So, if you joined February 2, and the title of the latest post was "Peas and Carrots," it will report that as that latest post until you update it. If I click on the link a week later, it will take me to your homepage, where I may see that you've published 5 new posts since "Peas and Carrots." Not a huge deal, just make sure that you update your post title and date on LF each time you post. It's still my favorite way to follow and be followed!
I look forward to reading your new posts.
