Tinny: Can it be installed on my shared hosting space or is it only for intranets?
You can download it
and install it wherever you want. There is also a virtual machine version if you want to try it out.
Which, in your opinion, is the best wiki installable on your web host?
It depends on a few things. For a "pure" wiki, I like mediawiki
, the one that runs Wikipedia. But you might choose something else if you have different needs. For example, if you like PHP, want more than just a wiki, but want something integrated, then you might want TikiWiki
. If you want it to be just a single (albeit large) HTML file that you can run off a USB stick, you can use TiddlyWiki
, that has a plugin
to keep a copy hosted on a web server.
