I have been using
DotNetNuke
for a while and am pleased with it. For the most part, I see a lot of
smaller businesses and individuals use it. However it seems that over
the last year or so, I have seen an increased presence in larger
businesses. Recently I gave a presentation at the
Alabama Code Camp
on custom module development for DNN3.x. I was asked to give it again
on Tuesday for a client in Birmingham, Alabama. This client is a large
company based in New York. They have started using DotNetNuke for some
intranet needs. I think it could prove to be a great cost savings for
larger organizations that have the need for what DotNetNuke can
provide. A lot of time and effort goes into trying to build frameworks
similar to what DotNetNuke provides. Don't reinvent the wheel!
