The New York Times reports that ThinkEquity Partners, a boutique equity bank, has started a blog to collect ideas:

"ThinkEquity is betting that the blog will attract analysts, bankers,
investors, venture capitalists and anyone else interested in talking
about growth investing, and in the process, help the company generate
ideas. The firm’s research is available to all and, once registered,
anyone can post feedback on the site."

I see this as a similar trend to industry research analysts blogging – an excellent shop window to display their know-how, and even to improve the advice they give.
