Others may already be aware of the site Scoop.It but in case you are not I thought I would introduce it. It's one of those sites which Google seems to love (which is always a good thing these days!) and it certainly helps me to get stuff indexed.
It's a cross between a number of other sites and has both a free and paid for version - I have opted for the paid version because it suits my needs but you can do exactly what I do with the free version just on a smaller scale and with a little less customisation.
Rather than waffle on about it let me show you what it looks like and then answer any questions. Once you have one set up you use a bookmarklet on your toolbar to add your pages and other peoples to your Scoop (I tend to do Niche ones) and you can also suggest that people add your content to their Scoops.
