Recently we worked on a project with intent to use AnswerHub as the primary vehicle for user interaction. After spending some time in AnswerHub’s admin we discovered that they don’t provide anything that you cannot accomplish with easy under the WordPress hood. While AH supplies you with a OSQA solution, WP gives you a full suite of options:

• Q&A with Sabai Discuss
• Forums with BBPress
• Knowledge Base with Pressapps
• Social login with Userpro

All together these solutions greatly outperform what is available with AH. Plus, being highly customizable, WP has an edge over AH in terms of scalability, flexibility and ease of installation.
