So, you've got a blog and you want a wiki to go with it. Or you'd like wiki functionality in your blog. Or something like that. How to do it? It depends on what you want to do:
1 Getting A Wiki And A Blog to Work Together
So, you have to ask yourself - do I just want every wiki entry/update to be a blog entry/update? If that's the case, then the simple solution provided at WikiBlogIntegration can help 1 - but only if you can sufficiently customize either the format of the mail sent by the update notice from your wiki, or if you can sufficiently customize the format that the mail that the blogging tool accepts. (Blogger appears to not care about the format of mail sent via post-via-email as per http://publicmind.blogger.com/enduser/group.jsp?node=116 , but does require Blogger Pro for that.)
Or, alternatively, you could also ask yourself - do I just want an RSS feed of the changes to my wiki? If that's the case, there are some wikis out there that support RSS feeds of changes by default.
One nice thing about a wiki is that linking is natural - you can create a link to a topic that should be there, and if it isn't, that's ok - when you follow it, you can create it then - instead of getting a 404 error. If all you want with your wiki/blog integration is to easily link to your wiki, that's fine - go ahead and link to the page even if it doesn't exist. You can add it later.
So what if you want to link back to your blog from the wiki? No problem - just about all wikis support external hyperlinks, so there's no technical problem with that. Link back to a particular category or result from searching for a particular phrase? If your blogging tool supports specification of the category in the URL or searching via ?search=whatever+I+am+searching+for in the URL then this is cool too.
2 Getting Something to Be Both A Wiki And A Blog
There have been attempts at this. Many of them are add-ons to wikis to enable them to function as a blog. This is often without the advances of modern blogs, such a pingback/trackback, and often without RSS feeds, but all these technical limitations could be overcome with enough programming effort. The larger issue, though, is that wikis were not designed to be blogs - they were designed to be wikis - they were designed to be collaborative - and they were designed for things like updating pages and stuff like that. Blogs, however, were designed from the ground up to be web-blogs, which are logs - time-based chronicles of events. So there are two approaches - one of them is that already existing chronicle of events in the wiki - the RecentChanges - and another is to set-up a macro within the WikiCode that says "this is a log entry". As you may guess, neither of these is perfect in their un-weblog-like manner, as they still wind up corresponding to a WikiPage which, if the name of a suitable topic, might very well mean/require change/update later on - and hence the log-ness is destroyed.
So, what about add-ons to blogs to make them function like wikis? LiveJournal has a feature that is similar to this called Memories. According to http://www.ourpla.net/john/wikiweblogpim.html it should be easy to code a wiki in Frontier/Radio. If there is a search for the blog, then something like linking to a search for the term in the blog might be sufficient for some people's desire. (I know back when I used SIPS as my blogging tool, I often just linked back to past articles - not even searches.)
3 Standing Back
Ultimately there's a disconnect - some people think that when they're writing, they're writing about a topic - these people are great with wikis. Some people think they're logging an event - these people are great with blogs. Some people think they're sometimes doing one and sometimes doing another - these people are great at having two separate tools - wikis and blogs - and interlinking them. Some people think that they're writing both about an event and a topic - and these people need something that can be both a wiki and a blog.
4 Convenience
For many people, I suspect, the lure of wiki+blog integration is the convenience of being able to use wiki words in a blog, and have them auto-link to the wiki entries that may or may not exist yet. Sadly, no such good tools exist yet that I know of (unless the blog is already in the context of a wiki). There are serious design issues behind such a tool that would need to be addressed:
link wiki words found in the blog to the wiki entry only of the wiki entry exists?
what happens when a new wiki entry is created after the blog entry was made?
if the link to the wiki entry is transformed into HTML at the time of the posting to the blog, moving the wiki breaks the blog
if the link to the wiki entry is made at the time of the viewing of the blog (and thus allowing feedback with regard to whether or not the wiki entry is defined) then there is much additional overhead
if there is no feedback with regard to whether or not the wiki entry is definied, do we really want links into the wiki for all wiki words? What about words like MasterCard, which are naturally in wiki case but which we don't really want to have a wiki entry for? Do we really want to be putting all the various forms of wiki code in every blog just to specify whether or not the word should or should not be linked?
There are some ways around these:
If one uses tools like MozBlog or others that allow drag and drop of browser bookmarks into blog entries, linking to wiki pages from within a blog only requires visiting the wiki page first - something that doesn't seem that uncalled for.
If one has suitable javascript support and a good search for one's blog, one can put links not unlike: <a href="javascript:search('somethingLikeAWikiWord')">example</a> and then any page that had 'somethingLikeAWikiWord' in it will be in the search results.
