Choosing a Closed-End Emerging Market Debt Fund

I have been very impressed recently by a stock blog called "Where Is The Yield" (WITY). The writer doesn't tell us his real name but he does claim to be male, 26 years old and living in Israel. Recently, he recommended the newly renamed "Western Asset Emerging Markets Debt Fund". (ESD) He's right to note the discount of 15% being historically high. You can buy this fund for 85 cents for each dollar of assets. Now the fund does have a hefty 1.8% expense ratio which means to me that it better trade at a discount. That's a pretty high fee for a bond fund. I hold an emerging market bond fund as a nice diversifying aspect of my portfolio.
