David Sifry has published the latest in his series of reports on the State of the Blogosphere, noting trends and changes. As ususal, there’s lots of interesting material. One trend is a leveling off of the nunber of new blogs and posts, which he attributes in part to Technorati getting better at filtering out splogs.
As weâ€™ve said in the past, some of the new blogs in our index are Spam blogs or ’splogs’. The good news is Technorati has gotten much better at preventing these kinds of blogs from getting into our indexes in the first place, which may be a factor in the slight slowing in the average of new blogs created each day.
The spikes in red on the chart above shows the increased activity that occurs when spammers create massive numbers of fake blogs and try to get them into our indexes. As the chart shows, weâ€™ve done a much better job over the last quarter at nearly eliminating those red spikes. While last quarter I reported about 8% of new blogs that get past our filters and make it into the index are splogs, Iâ€™m happy to report that that number is now more like 4%. As always, weâ€™ll continue to be hyper-focused on making sure that new attacks are spotted and eliminated as quickly as possible.
My gut feeling is that since we’re better at dealing with Spam now, even some of the blue areas in last quarter’s graph were probably accountable to spam, which would mean that rather than the bumpy ride shown above, we’re actually seeing a steady increased (but slower) growth of the blogosphere. Hopefully we’ll be able to have a more detailed analysis of these issues next quarter.
The data on the globalization of the Blogosphere is also very interesting and, I think, significant. Here’s a facinating observation that provides evidence that the blogosphere is not just the plaything of the current generation of young people in the developed world.
Coincident with a rise in blog posts about escalating Middle East tensions throughout the summer and fall, Farsi has moved into the top 10 languages of the blogosphere, indicating that blogging continues to play a critical role in debates about the important issues of our time
