I do think a few features are missing that I find valuable:
* Search (you can add it as an external service I haven't found one I trust and like yet. * Comments, there are several third-party comment providers that I can use, I tried out Disqus for a while but I didnt like nor trust them. I look at using forum software for the comments but then I have to run that and I might as well stay in WP
Then there are a few plug-ins I use and like.
The worst part of using WP is of course security. I have switched to fully managed WP hosting so I dont have to worry too much about that. I do still worry about plugins but my provider does not allow a lot of plug-ins due to issues and I can totally appreciate that.
