There's a financial advisor who posts on SeekingAlpha who uses and recommends a strategy that is primarily based on dividend paying CEFs. To get his daily updates and recommendations, and to participate in the chat (which has a lot of investors unusually informed on CEFs, bonds, and similar investment vehicles), you'll have to pay a subscription fee of around $500/year, or maybe a bit more. His service is entitled "Yield Hunting" on SeekingAlpha, if you're interested.
Interestingly, part of his secret sauce is not just collecting dividends, but also capital appreciation. He uses modeling to recommend when to purchase the CEFs, typically when their Net Asset Values are at historically high levels and their share prices are at low levels. He will also recommend selling when those two factors are inverted.
It has worked extraordinarily well over the last few years, but then again almost any strategy has. Regardless, it's a good way to received divvy's on one's portfolio in the 8-12% range.
