Ask HN: Best sites for finance, hedge funds, private equity?

HN was the first place I thought to ask, as the crowd is knowledgeable in a wide range of areas;

I've recently become interested in Private Equity, Hedge Funds and that side of finance.

What are some sites I can become more immersed in these topics.

Not necessarily knowledge based, more so HN type aggregator sites or news and current discussions. Even good historical stuff.
