Hub pages is very useful to me to write and learn to write for a community who also writes, while the emphasis is on the writing rather than the actual promotions and marketing side, but you can add reviews over there, which is what I like to do with my affiliate promotions, plus you can also earn royalties off your hub page articles through adsense, ebay and Amazon through a revenue sharing filter, but as usual it is better to try and get more traffic to your hub pages from lots of multiple sources to be of any effect in your marketing campaigns.
If you fancy yourself a writer and feel that you could be a good reviewer of anything, then head on over there and see my hub pages for examples!
