I wouldn't know what to do with Pageboxes also (as I still don't know of what exactly I am talking about in the main comment in this thread), but my use cases for the general idea were two:
- Online communities. For example, groups of students of some area, groups of pregnant women, groups of people who like tiny houses, groups of people who do geocaching, people who like to save dogs in the streets and give them to adoption, people who like to shoot at birds, people who work with something specific. All these groups probably have groups of email, or Facebook groups, (probably more than one group, maybe various localized groups) where they chat and share interesting links, data and information. Then this data is lost, it isn't searchable by the people who know it exists (specially if they are inside an Excel spreadsheet that was emailed to all the groups' participants), it isn't knowable for people who joined the community later. This people will never know (or will know too later) that that interesting data was there, just behind a pile of emails and posts. There are a lot of examples of data that could be indexed (yes, I'm talking about database indexes) in interesting ways, but I will give none now, and lots of data that could just be organized in an easy way (categories, although I don't like this very much) and made searchable.
For this problem, Trello is a good option, but it is limited, it is centralized, it requires an "owner" of the Trello board to authorize other people, it cannot develop in an organic way, with few people starting to use, then other people joining, and people who don't wanna join never joining. It also cannot index data, just categorize and archive.
- Myself. I don't want a blog, but I have interesting data stored in my computer and my brain I wanna handle to the public over the internet, to whoever be interest in it. I have articles I can't find anywhere else anymore, I have spreadsheet data that should be presented as spreadsheets, I have articles I typed from old magazines, I have videos I don't remember how I got, I also have impressions of books, commentaries about lots of non-mainstream topics, and mainstream topics also, mainly atemporal things, that don't fit well in a blog. I could make a static web page and put all this there, but it seems too difficult for such a low value it will have. I also don't wanna do it because I wanna keep thinking about how would a non-programmer do it. I can't help thinking every people in my situation would: (i) do nothing; or (ii) make a blog, post everything there for two month and abandon the blog. I don't like abandoned blogs.
Pageboxes could do something for this, but I don't know how exactly.
