If you’re interested in .Net, be sure to check out XL-Dennis’ .Net & Excel. From the About page:
The blog is about developing solutions with .NET that targeting Excel. The focus is primarily set on how to leverage the developing tools on the .NET platform but it will also explore the options to connect Excel with SQL Server 2000 / 2005 via .NET
It’s on my blogroll.
Now that it’s advertised, I expect Dennis will edit that “with .NET that targeting Excel.”
