This is a thread from BlogEngine.NET on CodePlex. (Multiple blogs on same installation) 

I would like to see the current dev plan, if it exists yet.  If I knew we/they/you were going to use SqlBlogProvider, and even integrate it into the core, I would like to help.  If there was also a way to allow multiple blogs within a single application, that would be great too.  Should everyone just create a new branch?

If we don't know the future plans, dates, implementation, etc., we're stuck deciding whether to wait or risk going forward with an alternative branch and missing out.  Communication would be good.  I may be missing something.  I've stated recently that I spend more time modifying current BE.NET code than I ever do Blogging and I have over a dozen blogs.  1.5.1.22 is currently stable, from my perspective with SqlBlogProvider supporting all of those blogs on a single folder, with a single SQL database and schema.  The only (minor) issue is still creating multiple Web Applications and pointing them to the same folder.  I can live with that on an 8-way server with 2 GB of RAM.

These are the symptoms I could find so far, but I cannot isolate the DateTime property that is causing the Exception.More...

Update (10/17/2009)

BlogEngine.NET appears to be closer than ever to a Multi-Blog implementation thanks to work done by Jacob Proffitt found here: Multi-blog Obsession.  The SQLBlogProvider allows multiple blogs to be supported by a single SQL Server database.  Imaging the maintenance and resource requirements, compared with “n” blogs and “n” databases, or “n” folders with “n-times-x” xml files for all those posts.  Currently, this provides for a single folder and any number of application instances, all pointing at the same folder.  There may be a few potential answers to this, but only if someone deems it a problem.  I’m now running about 12 (BlogEngine.NET) blogs in a single location with a single database using the SQLBlogProvider.  A few details were worked out to bring this solution up to the 1.5.x version of BlogEngine.NET.  While looking at this, I’ve learned a lot about some new features and found some useful and straightforward applications of Linq to SQL.
