I'd say I've taken a bit of a different route than most of the folks here. My website,
www.loisbackstage.com, in addition to housing my resume, some testimonials from folks I've worked with, a list of upcoming productions & a photo gallery of previous productions is also the home to my blog. What do I blog about? Mostly stage management, although I also share recipes sometimes (usually show themed - for example, Guys & Dolls Dulce De Leche Cupcakes).
I started the site knowing that everything I blogged about would be public and that I have to assume any company I work with has read what I've written. But I have also gotten work because of it. I blogged last December of my goal to get some equity apprenticeships this year and had companies contact me and offer me opportunities. Companies that are now employing me as a CAEA member stage manager. I've also had people come up to me at shows and say, "Hey, I love your website - I really enjoyed your post about SM Kits (or Tips for Show Calling or whatever the case may be). For that matter, I've had people come up to me at bus stops to say they read my blog. I've also had professors assign my blog to their students to read because it is the real-life experience of someone making a living as a stage manager.
I know this isn't a road for everyone and it does require some thinking and planning. For example, any time I post about a specific show or process I get permission from those involved. At times I even e-mail them a draft and ensure they are comfortable with what I am going to say and make changes as necessary. I also decided at the beginning that I would never review shows on the site as that could lead to conflicts of interest.
I'd be curious to hear what some of you think about the site and having taken this route and whether or not you have any suggestions of things that should be removed or added.
