Until 3bubbles nobody has developed a way to tightly integrated chat into
the blogosphere naturally and specifically.

Blogs are communities based on communication — posts, comments,
cross-linking and trackbacks. The problem is that communication is slow.
3bubbles provides an alternative that is complementary to blogs by creating
real-time dialogue between blog readers and authors in a secure and
spam-free fashion

3bubbles unites chat and blogs to create real-time conversations in
the blogosphere.

A swicki is new kind of search engine that allows anyone to create
deep, focused searches on topics you care about. Unlike other search
engines, you and your community have total control over the results and
it uses the wisdom of crowds to improve search results. This search
engine, or swicki, can be published on your site. Your swicki presents
search results that you’re interested in, pulls in new relevant
information as it is indexed, and organizes everything for you in a
neat little customizable widget you can put on your web site or blog,
complete with its very own buzz cloud that constantly updates to show
you what are hot search terms in your community.

Goowy has rebuilt a number of commonly used applicatons (like email) in Flash. It includes traditional web services such as email, contacts, calendar, games and widgets. Goowy is highly interactive and, as you’d expect with a flash application – fast. Visually it is a very beautiful site as well, and I wasted a good amount of time today playing around with the applications (including some very addictive games).

Goowy is one of the first full featured internet applications that uses Flash 8. For more detail, see Mike Schleifstein’s post on Goowy, although I disagree with some of the conclusions in this post – Ajax, xforms and other technologies are gunning for some of these same applications right now.

Relevance in blog search is very difficult. Google-stype PageRank analysis, which looks at incoming links to a piece of content, simply doesn’t work because new content doesn’t have much in the way of links. Until now, no one has come up with a way to properly sort blog posts by relevance, and the general default way of showing results is “reverse-chronoâ€?, which simply puts the newest stuff at the top.

Sphere appears to have solved the problem, or at least taken big steps in the right direction. Their approach involves three key algorithms – an analysis of links into and out of a blog, an analysis of metadata around a post (links, post frequency, length of posts, etc.), and something Tony calls their “secret sauceâ€?, which is content semantic analysis to filter out spam and to understand what a blog post is talking about.
