The latest numbers are in, and Twitter is apparently growing at a torrid pace. According to stats just released from Nielsen Online, Twitter recorded 2.3 million unique visitors in August (US-only), an increase of 422% from the same period last year.

Moreover, visitors to Twitter spent 55% more time on the site on average - a total of more than 7 minutes per user. Those numbers point to rather robust growth for the site, especially considering many of its most rabid users access it through a third-party client like Twhirl or Tweetdeck.

One of the most requested feature from plurkers is the ability to 'mute' certain plurks so that they won't receive any future 'new response' notifications from it.

Well, be careful of what you wish for.

This will be one of the many more noise-reducing features we will be introducing in near future.

Keep the feedbacks coming and thanks for helping us make plurk-land a better place to hang out.

According to Plurk, the service is "a really snazzy site that allows you to showcase the events that make up your life, and follow the events of the people that matter to you, in deliciously digestible short messages called plurks." At first glance, I'd call it Twitter with a visual timeline.

Plurk has an emphasis on actions as opposed to clean slate message, and each user is offered there number plus a drop down list with actions such as is, thinking, was, asks and similar. Each "plurk" is posted to a visual timeline that includes drop down threads for replies. The service also offers "cliques" for plurk distribution and various privacy options.

The events that hit our system the hardest are generally when "popular" users - that is, users with large numbers of followers and people they're following - perform a number of actions in rapid succession. This usually results in a number of big queries that pile up in our database(s). Not running scripts to follow thousands of users at a time would be a help, but that's behavior we have to limit on our side.

Chris Kilmer and Tembrooke both ask if putting some limits on what users can do in our system would help, and they're both right. We have some limits, and we're adding more. Legitimate users should never notice them, but these new limits should help mitigate the worst case failures and attacks.

• Twitter could disable the auto-follow that is used on a number of Twit accounts. This would make these users (like @Scobleizer and @BarackObama) have to manually follow people and it would likely reduce the number of people they follow.
• Twitter could limit the number of people someone could follow. Facebook has a limit of 5,000. Mathew Ingram notes that some people want Twitter to apply follower limits. Ryan Spoon makes the case that Twitter needs its power users. Facebook's 5,000 friend limit sounds far too low for Twitter but do people really need to follow nearly 90,000 people like one user did? While there might someday be a cap on the number of people someone can follow there should never be a limit on how many followers someone can have. It wouldn't be right to tell someone they couldn't get Barack Obama's tweets just because 30,000 other people were.
• Twitter could try harder to stop spammers. There are some obvious adult spammers on Twitter and some that use tricky means to get people to follow links. Others come aboard and quickly follow tens of thousands of people in a few days. They could try and block the follow scripts some of these people must be using.
• They could also look at limiting the number of tweets a person can send per day or per month. Look at this list and you will see a list of 100 Twitterers who each have sent a total of more than 25,000 tweets. Some of them have sent over 100,000 tweets.
• Some Twitter users have also suggested paying for Twitter.

Technology has made staying in touch with your friends and family both easier and harder: living a fast-paced, on-the-go lifestyle is easier (and a lot of fun), but it's more difficult to keep track of everyone when they're running around at warp speed. That's why we're excited to announce that we've acquired Jaiku, a company that's been hard at work developing useful and innovative applications for staying in touch with the people you care about most -- regardless of whether you're at a computer or on a mobile phone.

Current Jaiku users can still use the service normally, and new folks can sign up for an invitation to the service when we're ready to expand. We plan to use the ideas and technology behind Jaiku to make compelling and useful products. Although we don't have definite plans to announce at this time, we're excited about helping drive the next round of developments in web and mobile technology.

Pownce is a way to send messages, files, links, and events to your friends. You'll create a network of the people you know and then you can share stuff with all of them, just a few of them, or even just one other person really fast.
