GoDaddy shared hosting is certainly not the plan for those who need any DNN-related handholding for manual installation or ongoing DNN support.  It's also not the plan you need if you require maximum control over your environment (read: full admin access to all systems and components).  I have found, however, that GoDaddy can be perfectly fine as a host as long as you know the limitations and are willing to provide your own DNN-related support.
 
Since you've heard nothing but problems from others, count me as the first person to endorse GoDaddy's shared hosting as an "acceptable" plan for most plain-jane DNN installations by those who are comfortable with not having DNN-centric support from their provider.  Over the last several years I've set up and maintained a number of DNN sites under GoDaddy without issue.
 
...and just to be fair:
I've more easily set up and maintained sites on hosts other than GoDaddy, but then all of those hosts are also more expensive (get what you pay for?).
 
Cheers!
