First, there was alltop, now there’s Speaking Pro Central. Speaking Pro Central is a new website which aggregates content from many different speaking and presenting sites.

What’s special about it is that it has a clever search feature that allows you to find the top posts “according to social signals” for a given keyword.

Tony Karrer is the driving force behind the site. He put together a really useful post on Twitter and webinars simply by using the search facilities on Speaking Pro Central.

Speaking Pro Central is particularly useful if you don’t want to subscribe to all the speaking and presenting blogs – but just want to be able to find the content you want when you want it.
