In response to Rob I thought I'd share how poorly I'm utalizing my server... As opposed to creating an actual scalable blog I have continued to perform my "simplicity" wins model for BlogX... The underlying database is my file system... the files are simple XML blobs that I use System.Xml.Serialization to read...

As for my server, I'm keeping the same model. I started hosting a few people at work on an extra machine in my office... 5 people became 10... 10 became 20... i'm up to around 50 people on the machine. All on a 512MB P4/3Ghz...

Yesterday I finally got backups going when a senior manager asked what would happen if the server went down :-)

I'm still adding people by hand - no fancy admin tool. I give each user a directory under inetpub\wwwroot, with full read/write access and a SMB share... I edit the homepage for the server - to be a directory of people - and then send them a mail.

The worker process is running at about 250MB, but my max pagefile usage is 35%... the response time seems fast, and nothing seems to be breaking yet...

How many people should I expect to host on a 512MB machine?
