Wordpress has risen to be a powerhouse on the Internet that now dominates the blogosphere. It was started by the (now) 25-year-old Matt Mullenweg. Last week he was on This Week in Startups with Jason Calacanis. On the show Matt revealed that Wordpress has such a strong presence on the Internet that at least one in three Americans online have visited a Wordpress blog in the last month.
Wordpress lets you use thousands of powerful plugins that complement and extend the platform in a variety of ways. I have scoured the Wordpress Plugin Directory to find the very best plugins to share with you in this post.

Millions of people who blog don’t want to deal with hosting their blog themselves, so they use a blogging service instead. There are many things that factor into the choice of blogging service, but one of them should always be site reliability. After all, if people can’t access your blog, it won’t get read.
For this survey we have monitored the websites of nine blogging services for a period of four months to see how much downtime they have. The included services were Typepad, Blogger, Wordpress.com, Blogster, Blog.com, Vox, Squarespace, Windows Live Spaces and LiveJournal.

Yesterday a Twitter post (a tweet) by Mashable’s Pete Cashmore became so popular that traffic from Twitter crashed a blog. This sounds very similar to a common social media phenomenon originally known as the Slashdot effect (and later also the Digg effect), where a post on a popular social media site pushes more traffic than the target site can handle.
An interesting thing here is the mechanics of Twitter, which is fundamentally different from Digg and Slashdot. It’s not a social news site, with a front page that all visitors go to. We won’t go into the details of how Twitter works, that’s better covered elsewhere, but it’s worth noting that it’s a very different beast. It will be interesting times if Twitter is about to join the ranks of Slashdot and Digg as a potential “site crasher”.
For lack of a better word we will call the phenomenon of sites crashing as a result of traffic from Twitter, “the Twitter Effect”. (Or perhaps “the Tweet effect” would be catchier…?)
But now on to the big question: How could a single tweet generate that much traffic?

We all know that Wordpress is popular among bloggers, and Movable Type as well. But HOW popular? And what other platforms are being used? To find out, we went through the Technorati top 100 blogs and investigated what blog platforms they are using. It turned out to be a highly interesting survey with plenty of surprises along the way.
As a by-product we also found out some interesting things about the more popular blog networks. For example, did you know that Weblogs, Inc. and Gawker Media together have 22 of the top 100 blogs?

The blog search engine Technorati suffered from both downtime and slowdown during large periods of December 12 and 13. In those two days, the Technorati website was completely unavailable for a total of more than 9 hours.
There are indications that the problems may have been caused by database issues at Technorati.

Many of the blogs that have a huge following today go back to much more humble beginnings. This post is a look at how they got started and what they looked like in their early days, compared to today.
