A relatively late entrant to the www.twitter.com phenomenon, I started uploading my blog posts on my twitter account.Here are some insights which I saw in action and maybe they are common knowledge but here goes-
1) Twitter automatically converts links into www.tinyurl.com links so it shortens even the longest link that you have
2) Uploading address book, including anyone who ever wrote an email to you as part of a discussion or reading group, takes a tiny amount of time. Then click follow all ( or at least those for a particular profile –here analytics and data) and you are off.
3) Twitter manners seem to consider it customary to follow people who are following you.Thus an audience or initial leads are assured. Rest content is king.
4) Reading tweets ( or twitter messages) is a great break as it gives you a real time insight on what is happening within the world of your domain or people who belong to same profession or same personal profile as to you. However writing personal tweets takes time,and a healthy dose of self love.
5) Twitter is free. And there are enough twitter tools to ensure it gets updated from your RSS feed automatically so it is one more tool to ensure publicity for your self or your organization.
6) Search for people giving or receiving same services as you provide to get maximized target response.
7) Link up your Face book, and your Yahoo instant messenger with Twitter using applications built exactly for this.
No ,LinkedIn does not have a Twitter app but that should change soon.
8) Watch out for useless spam stuff from people whom you don’t know well.Spamming or just being reported leads to suspended accounts and much useless grief.
Happy twittering with tweets on www.twitter.com ( ..what a tongue twister !!)
And an update from my favorite tech blog http://bits.blogs.nytimes.com/–
Starbucks dishes out updates on special offers and nutritional and store information using Twitter. The online retailer Zappos, Comcast and Southwest Airlines have also created official accounts on Twitter to interact with consumers and respond directly to complaints.
Bank of America’s Twitter stream is maintained by David Knapp, a representative in Phoenix.
And why is http://bits.blogs.nytimes.com/ my favorite-
It shows blogs with better command of English than of technology are better reading than blogs with superb grasp of technology but not of English.
In case you want to say hi/ tweet/shout ……..this is where, my twitter sit ’er

DECISION STATS 
In a Business Organization, Micro-blogging can increase productivity and contribute to Collaborative Organizational Knowledge. I see cyn.in proving it right by providing cyn.in Desktop.
cyn.in Desktop is integrated with cyn.in collaboration software that has core collaboration applications like wiki, blogs, workspaces, file repositories, media repositories, shared Calendar, contextual discussion, Search and Workflow (Role based Access Control). Users are created in cyn.in main site and their access rights are provided to them based upon their role in the organizational hierarchy.
Cyn.in Desktop (an Adobe AIR app) inherits user’s workflow (access rights) from main cyn.in site and delivers the activity stream to the authorized users. Activities e.g. If someone uploads a file in cyn.in main site, the other authorized user receives a notification from cyn.in desktop and can instantly comment (Tweet) on the content. Similarly another authorized co-worker can add new comment on the same content OR can reply to previous comment (Re-Tweet). The important thing here is that the comment and re-comment (Tweets or Re-tweets) gets structured in ‘Threaded Discussion’ form attached to the content container as “discussion”.
ReadWriteWeb recently mentioned ” The cyn.in client is beautiful implementation of how microblogging could (and perhaps should) work for businesses”.
