Yesterday I wrote my 50,000th Tweet.

I have seen hundreds of new companies in the five years since Twitter came out (its birthday is today). None has affected my life as much as Twitter has.

Thank you Jack Dorsey. Thank you Ev Williams. Thank you Biz Stone. Thank you to the team of hundreds of Twitter employees.

We’ve had a rocky relationship, yes, but that’s the way it is when I spend so much time with one service.

Thank you for bringing me the world and changing my life.

I’m @scobleizer on Twitter and if you are a geek I want to follow you. Leave a comment here and explain how you are into tech.

UPDATE: I’m very honored that BBC says that I tweeted one of its favorite tweets and that FT says I’m one of the top five most influential Twitterers.

Back in the 1980s when I worked in retail I noticed that people were influenced by other people in their purchasing decisions. Many times people would change their decisions simply because the person next to them decided on a different camera. We are, even as adults, influenced by what others near us buy.

So that’s why I was interested in Wantlet, which mixes social influence into shopping decisions. You ask your friends whether you should buy a Nikon or Canon camera, or if you are a woman, whether this dress or that dress is better.

Wantlet helps out by providing a way to get feedback from other people. Here Kristian Luoma, head of product, shows it to me. Will you use a system like this? Or, will you wait for your friends to tell you to get on it first?

I used to really be into chat rooms, but since blogging, twittering, and Facebooking came along I found it just wasn’t that interesting to me anymore. There were better, and more focused ways, to talk with people about things I cared about.

But Leah Culver thinks she can build a future for chat with her new company, Convore, and fix some of the sins that older chat systems have. Funny, the engineers at Rackspace love IRC too, just like she does. But that’s pretty geeky. Can she get the rest of us to join in?

Based on the new people who are inviting me into Convore chat rooms it definitely has a chance.
