What is the best way to build a blog from scratch?

A vague question I know. I do know what I'm doing, I'm more or less looking for advice while I have the chance. So I'll leave the comments wide open for your opinions. Anyway, here's the background. I custom made a website with a public face and a behind-the-scenes administration side to take care of messages dropped on the site, etc. Well I want to add a blog. I am basing my entire website on ASP.NET using an Access database. I know that's not wise but I do have reasons for going with Access.

So with each post (that could be 10 paragraphs or more), should I save all that data into one record in the database for easy retrieval (what is the size limitation?), or should I stream write it to a text file and mark the text file name into the database?

The concept is rather simple, but coding it is the hard part. Also, is anyone jumping out of their skin yelling at me to get away from Access? I use it for simplicity and the convenience of portability when it comes to the actual database file.
