Yes, DealFetch.com.au is yet another group deal aggregation site, but at least it has a potentially worthwhile twist. The site add location details to deals and lets you pick ones near your suburb, so you can filter out cheap restaurant meals that require you to drive for kilometres in peak hour traffic.

If you don't want to track a lot of daily deal sites, there are already lots of aggregators. DealWatch is another contender, offering summaries of deals from five major providers and across 14 cities.

Lifehacker rounded up group deal aggregators back in January, but like the group deal market itself, aggregators continue appearing. Grouped is yet another contender, rounding up offers from both deal of the day and group deal sites.

Search site IceRocket gives near-real-time results from the web, blogs, Twitter, news sites, images, and videos (phew), but its Big Buzz feature conveniently mashes it all onto one page. For those "What's going on?" moments—such as when, say, a plane crashes into the Hudson River—it's a great spot to get a quick scan of what's going on, and what's being said, on one page. IceRocket's advanced preferences open up some results-cropping tools. For those looking for a serious bathing in information, you can also grab an RSS feed from your search results. IceRocket is free to use. IceRocket Big Buzz

Web site Swurl aggregates your online activity in a simple blog-like format. From del.icio.us bookmarks and favourite YouTube videos to Twitter posts and Flickr photos, Swurl pulls it all into a simple blog-like interface. On the surface Swurl sounds similar to previously mentioned FriendFeed, but it's actually got a much different feel and offers a lot of customisation. Swurl's timeline feature stands out most, placing your links, photos, and other activities on a calendar timeline. For a nice example, check out Swurl founder Ryan Sit's Swurl page; if you like what you see, starting your own Swurl is free.

Let's face facts—you're probably Googling yourself on a regular basis, whether for pure ego satisfaction or monitoring of your professional image online. New search aggregator Addict-O-Matic just happens to be great for seeing how you "look" online, as it focuses on returning results from the top social networking sites, Web 2.0 services, and blog-watching services. Of course, it's also a great tool for monitoring a topic or another person across the web's wide expanse, but once you add Addict-O-Matic to your Firefox search bar options or just as a bookmark, you know you'll be heading back to satisfy your online-mirror-checking fix.

US-centric: Got a product you want to find for a steal, but not enough time to run through Fatwallet, Slickdeals, BensBargains, or any other of the deep-discount sites? Deal aggregator Combyo gives you results on any product, filtered by date, source, or category, and lets you set email price alerts for anything that's just not cheap enough yet. It's fairly similar in purpose to previously-mentioned Dealighted, but the interface is a lot cleaner and easier to run through (Original Dealighted post). Combyo

To be honest, BitTorrent aggregator LookTorrent wouldn't be much of a competitor for its Ajax-powered counterpart YouTorrent, except that YouTorrent has dropped most of the popular torrent sources in anticipation of a squeaky-clean sale. What LookTorrent does is provide a top frame to search for torrent download links, and links to 25 sources, one of which will likely have even the most obscure files. If nothing else, LookTorrent's home page is a nice catalog of sites to look through while you're on the hunt for that special download.
