BTW, I've also found it quite handy for me as an Admin to monitor the visitors activity. Just leave your fronpage opened in a browser tab, and you'll get all the hot news in real time
This and that actions are taken every other minute at your store: new customers are registered, items are added to the shopping cart, new reviews are submitted, etc. But all these activities fall through the cracks for your visitors and they can’t even imagine what is going on right now at the store.
With the Activity Stream extension for Magento, you can let your customers see what is happening at the current moment. Recent actions are displayed in the block that can be easily added to any place of your site and doesn’t affect any elements of the page. Moreover, you have a possibility to hide some activities from your visitors and focus their attention on the required ones.
The Activity Stream module makes your customers feel that they are not alone on your website and shows activity streams like “Mike is viewing Electronics”, “John has logged in”, or “Annett has purchased HTC Touch Diamond”. The effectiveness of the extension is clear: visitors are influenced by activities of other people; they take the situation as a recommendation for further behavior and start experimenting and discovering your store.
