It works for me. Current version of wordpress [3.6] broke the wiki source code however around the function $wpdb->prepare() which now requires two or more arguments. Current wiki code only passes one argument. I fixed this issue by adding a dummy value of 0 as the second argument in these classes:
WikiDashboardWidget line 12 of wiki_dashboard_widget.php
WikiFeed line 44 of wiki_feed.php

I think it does what can be expected. It makes it easy to add wiki pages to your wordpress site. Installing was like most plugins, I installed and it just worked ??

Small issues with ShareThis plugin since the sharing code gets included in the edit field if you edit a wiki page. So after saving you will se 2 instances of the share buttons, which gets included the next time you edit the page and so on… Guess the same will apply for any plugins that add to the content.

Unless you want to pay for OPEN SOURCE software I do not recommend. How it made it past the wp plugin team is beyond me. There is no settings page for the free download. I guess developers forget that charging for code make the software not valid for open source. You can charge for support but not code that the line do not cross it. As I can’t review this because it has no settings this may be a good software but I guess bad practices always give you better service. It’s like betting on the cheater to win the race.
