Hi, I wanted to install a plug-in that allows readers to see the number of views per post. Is there any such plug in available for wordpress.com? Either directly or through a paid upgrade?
Hi there, it is not possible to install plugins on WordPress.com due to security reasons. Purchasing a paid upgrade does not change this. The good news is that we have a built-in feature that is close to what you are looking for: http://en.support.wordpress.com/widgets/top-posts-widget/
While this widget does not display the number of views, it does display the most popular content.
Alternatively, if I switch to wordpress.org, I understand that I can install an external plug-in, but do I still get my new posts listed with hashtags in the reader for people to discover?
Yes, if you move to WordPress.org, you'll be able to install external plugins. You'll have more flexibility, but more responsibility, too (paying for hosting, keeping your installation up-to-date, backups and security, etc).
The Reader and Topics are for WordPress.com blogs only, so your blog will stop appearing under hashtags if you move away from WordPress.com.
