Re: stats, likes and shares
Our stats are not real time stats. The data is cached and takes hours to update. See here for more on stats > http://en.support.wordpress.com/stats/
Likes and shares are misleading when you are talking about page view stats. Your followers and anyone with a WordPress.com blog who is logged into WordPress.com can read, "like" and "share" your posts in several locations such as in email and the Reader without ever clicking into your blog and creating a page view stat.
You can control the length of the entry sent out on your RSS feed here > Settings > Reading and choose the "summary" setting for your RSS feed or the "full text". If you set it to summary then visitors have to click into the blog to read the full post.
