August was the first month of the year in which tweets sent by Twitter users decreased. In addition, user registrations decreased for the second time this year (month-to-month).

Matthew Daines, the lead developer of the Twitter app, Twellow, has shared a couple of graphs illustrating the number of Twitter user registrations and number of total tweets for the month of August.

"The first time user registrations decreased was back in May, but that was attributable to the Oprah effect," says Daines. "The DDoS attacks probably had something to do with the drop in traffic for the month, so it will be interesting to see what happens in September."

You probably recall last month when Twitter's service was interrupted frequently. This was the result of denial-of-service attacks against both Twitter and Facebook (among other sites).

Still, it's hard to tell how big of an impact the attacks really had on Twitter's numbers. You have to wonder if Twitter is getting closer to leveling out, or if it's getting better at stopping spammers.
