Social Oyster is a tool that allowed users to share their Web activities to their friends. In order to use the functionality rendered by Social Oyster, you need to register an account with them which they called it “Your Oysterpass.” Upon you sign-up with them, you can fill-up Your Oysterpass, in other word, your profile completely with all the fields such as your favorite, your business URL, etc. Besides, they allowed you to embed your profile to your Website or blog through a one-click button called Oysterbutton. On Social Oyster, you’ll find that all the features are labeled with the word Oyster, and I only can decipher about its offering after playing with it for a couple of minutes.

Meanwhile, I believed Social Oyster is a FriendFeed (I will profile this startup in later stage) clone. Though it remains coy as it won’t say what is its ambition and which services it intends to provide in the near future on its Web site, but from the “OysterLine”, you can easily aggregate your Web activities as well as able to find out all your friends’ recent activities from this particular page. In addition, Social Oyster also build a “Public Oysterline” page which allowed users to see all the Social Oyster users’ activities in a real-time basis. The Oysterline is an ajax-realtime-reader, click on the item will bring you to that page, regardless it is aggregated from Flickr, YouTube, or del.icio.us, etc.

Social Oyster hasn’t proved that it can do well in the RSS aggregation at this moment, as I aggregate my Twitter activities to this Social Oyster, all the links appeared to be a long text, not the URL link that I expected. However, Social Oyster is seeking to offer its users a new means of searching user profile on the Web with the launched of a social search engine, users can type an username to conduct a profile search as well as use the “places” to find users in their neighborhoods.

Sweetcron is a new open source software that helped one to create a self-hosted lifestream service. Currently developed in Japan and in Alpha phase, it probably will be released soon by its creator, i.e. a php programmer called Yongfook.

At this moment, very little information about this newly open source software, but the front page of Sweetcron stated that it will be an open source RSS aggregator, with a bunch of php source files that one can easily debug and improve from it, and of course, a default CSS theme readily offered to the users. Since it is an open source software which you can self-host it with your own domain, it also mean that you need to configure the update yourself.

Swurl is a new lifestream service that can pull your latest activities from nineteen (currently supported up to 19) Web services into a blog-like format profile page. Upon you sign-up to this Swurl, you can straight away start to aggregate all of your online activities, even they didn’t require you to check your email for email verification. Playing around Swurl know that it play an important role in displaying all of an user’s Web life in a more systematically way and without any doubt, I think they’re in the middle in prospecting the bloggers that run their personal blogs with a focus on the personal life.

Since Swurl is relatively new on the Web, but they capture the opportunities not only supported pictures (Flickr), social network (Facebook), link (Digg), blog (wordpress), video (Youtube), review (Yelp), but they also supported the new frontier of social media such as FriendFeed. What is the main difference you can find on Swurl is the design, a blog-like format, with all the comments are systematically integrate to the user’s profile page. Although the first impression of Swurl profile remind me a lot of my previous blog theme, K2, but you can easily change the heading of the profile so that it suit your online identity. In many instances, social media aggregator like Swurl will help users to pull information through RSS feeds, but you’ll find it useful when you know the information obtained is usable.

One of the built-in features I think is very interesting is the “Timeline” view. From the Timeline view, I knew that I’m not everyday engaging on the Web, I’ve my off-Web real life too. However, the only thing I didn’t like is all the feed entries appeared on the Timeline have been reformatted to the Swurl URL link.

For the Web developers, there is an API of Swurl for them.

Profilactic is a social media aggregator that launched in the end of 2006. It is focus primarily in pulling all of your online profiles into one place. In other word, if you’ve Twitter, blog(s), Flickr, YouTube, etc., what you need to do is sign-up to Profilactic and then start to pull all of these activities under the accounts aforesaid into your Profilactic. On the other hand, you also can see everything that going on with your friends in all the sites they used, provided they’ve a Profilactic account. You can imagine it is very cool when you can interact with multiple sites at once. This type of aggregator or better known as lifestream mashup is pervasive now on the Web. In using this type of service, you also can create a badge, i.e. My lifestream and put it onto your blog, or some other social networking sites.

Social media aggregator is not a very special asset that can earn a startup supercompetitive for an unusually long time. FriendFeed also doing it, with the intense competition from Socialthing!, iminta, and Plaxo. However, Profilactic is trying to outstrip its competitors in a “number game.” They made a comparison with FriendFeed in March this year, in a post entitled, “Profilactic vs. FriendFeed,” with the statement that Profilactic is supporting 155 social sites. Now the number has increased to 186.
