The comments I saw were on the HGTV Star blog, the only one that I remember that seemed to have a blog was Jessie, I think it was called Design Diva but I'm not sure, she used that as her posting name. This site is so hard to navigate but I will try to find it for you. I did goggle it but she had no direct comments on her blog at that time. I think it was right after she left.
Well I was close, Jessie's blog is Design Daredevil, I just goggled it and there is nothing on there but some pictures from espisode one. She said she would write a deatiled report but it would take awhile.
So the others that posted just used their name or twitter address so I don't think they have blogs of their own.
I know some have Facbook pages, Karl & Meg did. I might see if anyone from this season does.
