• WordPress is getting complicated day by day, I like the open source version where you are hosting it on your server, but with wordpress.com its too much of a time waste. 
• There are thousands and thousands of themes, most of them are useless and you will never find the one theme that could help you with what you want to do.Mine is a tech blog and i needed a theme that would support code syntax highlighting and at the same time look pretty. I am sorry to say but it never happened.
• You can't use plugins of your own if u are using the free version at wordpress.com.
