I added Dan Bartels' BlogStats control to CSBlogs today. You'll find it at the bottom of my left-hand sidebar. I didn't employ it with Dan's "encapsulated" controls approach, but I did use his source for the ASCX and .CS file. Thanks, Dan! Those, with the tag to be added to your parent usercontrol is located here. Its a more simple approach than Dan's, but you need to read Dan's article to decide for yourself what's best for you.
I've followed Dan's lead in dotText and CS for a while now and do need to think about future CS releases, as he discussed in his control encapsulation article. Bottom line, you can segregate your mod classes and controls (which I do) but there's just no way to make the changes you need to make without mucking up the base package. You can encapsulate and inherit from base classes, but base classes can change on future releases as well.
More thought and more discussion coming on Approaching CS Mods, to be sure. In the meantime I'll keep separating mods and commenting embedded source changes with my signature "// DBVT somethin somethin" and see what happens when 1.1 is released. Then again, my new BlogStats control tells me I've entered 662 posts, which I've confirmed to be accurate. That's a lot. Maybe I'll quit at 700 so I don't have to worry about it.
