Measure twice

Measure twice and cut once. That's sage advice when working with physical material. The same adage need not apply online.

I'm looking for a site which allows all of the following:

• blogging (like here :)
  
• file posting
• wiki (so others can contribute)
• option to turn off advertising for a fee (like wikispaces.com)
  
• option for password access (like PBwiki.com or netcipia.net)
  
• "unlimited" space (more than the measly 10 MB available at PBwiki.com)
• ease of use (like insight.wetpaint.com)
  

These capabilities are certainly available. But not in one spot. I thought the solution was Netcipia and started up insight.netcipia.net, but they aren't reliable at this time. They don't even have an option to backup your site right now. That's scary. I can't build a blog on a site that may not last.

So I'm relegated to using different services until I find what I'm looking for. I'd rather not host my own site, because of the hassles on maintenance.

I'm a big fan of Google. So I figure that by blogging here, I'll at least have some assurance that this service will remain in service :)
