There’s a lot going for the spreadhsheet approach but I do see what you’re saying. I think that, if I could freeze the columns as well as the rows, it would work better.

I’ve tried setting up a page on the wiki I created some time ago. The Twitter entry would look like this:
http://prblogs.wikispaces.com/Twitter

It’s easier to read, and probably easier for people to edit too, but you might see the problem I see: I would have to create a separate page entitled, say, ‘Press announcements’ if I wanted to enable people to do it by activity then listing the resources within that.

The use of tags – along the bottom of that page – goes some way to fixing this but not all the way.

I’m not sure a blog would do it either.

Hmmm. There must be another way. Any ideas anyone?

I’m not familiar with Wikis so wouldn’t be able to comment on that side. Would a blog work? You can include update content via postings (contributions), control the tags and then go from there. Eventually, if you really want to be ambitious, publish an ebook with the top information.

I would love to help – so let me know if you want to continue discussions offline.

I could tag a page, say, ‘twitter,theory,promotion’, ie it discusses the theory of how Twitter could be used in promotion. But what do I call that page? ‘Twitter’? It’s not just about Twitter. It’s about how Twitter can be used, in theory and in practice, for PR. I could split this page into two, have ‘theory’ and ‘practice’, but then how would I reference it by PR activity? Set up another page, entitled ‘Promotion’, and list the exact same content but in a different order?

Following from that, what if people use non-standard tags when they’re creating a page? Suddenly you end up with loads of tags that could mean the same.

And what if people don’t update the navbar?

I still think the spreadsheet approach works best. The logic and the structure are interlinked, and by adding one vertical/horizontal category you automatically add to the other axis. And the cell size also forces quick, short entries rather than sprawling explanations. I want this to be a look-up, not an encyclopedia.

But I’m still prepared to be proven wrong.
