Sometimes I regret starting this blog in my own name and wonder if I might be more productive with it if I’d chosen to be anonymous and felt safer talking about certain aspects of my experience in graduate school. For example, I don’t feel like I can really address some of my feelings on the theatre produced by the department, or certain dynamics between professors and students, or even students and other students. Not that I would want to turn this into a gossip fest, but it might be nice to tease out some of the complications of working toward a PhD with an eye to the actuality of working in a specific department.
On the other hand, as I care about theatre, theatre pedagogy, and how theatre departments operate within the larger field of academia, these are issues that I will always grapple with and probably now is as good a time as any to develop strategies that are respectful to my colleagues while allowing me to be as honest as possible. This is a challenge for me because bad theatre and poor teaching are among the things in this world that make me get angry and very, very riled up. Again, however, now seems as good a time as any to start learning how to handle this challenge.
Any tips? 
Funny. As I am beginning to migrate over to a blog that is really me, you are beginning to see the benefits of hiding behind a nom de guerre. I am not closing my other site, and I will continue to write my more snide and obnoxious commentary on that site while the new site will focus on thoughts and ideas that are appropriate for people to know who posted them.
I would suggest that you just suck it up and start a gripe site and blog all your frustrations out on that. You don’t even have to buy a new domain (although you certainly can). There are other options:
1) you can create a blog under this domain or any of the others you already own and keep it hidden 2) you can create a blog under this domain or any of the others you already own and just not advertise it 3) I’d be happy to host your gripe site on one of my domains
I think that that is all I can offer you as far as advice.
