*The Mystery begins
Not too long ago, Shrikey was asking me what I had done to show my twitter status in Yahoo messenger, that time, I was using Digsby, and I was updating both my Gtalk and Yahoo statuses using that, I thought that he mistook my Gtalk updates to be twitter updates and told him the same.
Few days passed by and then one day when me and Phani were experimenting on Apache server I tweeted about it. Later, Venu came online and was asking Phani, what he was doing on Apache.. we were thinking that he was observing my twitter feed and hence got to know of it. But he said that he saw it in his Yahoo messenger. This time I was not using Digsby neither had I updated the my Gtalk status. He even stressed the fact that it was in Y! Messenger and told the location where it was visible.
*What could it be??
So it had to be some service that I used and forgot about. I then started scanning my memory to see what it could have been, but all tries returned no results. Finally I visited everything.yahoo.com its the exact thing I needed, an exhaustive list of all the web services that Yahoo! provides.
I found some really crazy things via this.. a site called omg.yahoo.com which has a totally "different" layout, something called myweb.yahoo.com that's going to be shutdown soon (redundancy and Recession :P ) then there was as developers.yahoo.com where I got to know that there is a thing called "Yahoo Query language"(No wikipedia entry for it even!) These yahoo people sure are doing a lot of stuff. They have services starting with every letter of the alphabets but Q and X, I wonder what they're waiting for.. just 2 more and your collection is complete!
*The Root Cause!
After looking into those things, I finally found out which place made my yahoo status automatically change to the latest twitter status.
It was MyBlogLog.com. I recently went to that place after finally clicking on a link to it, in one of the blogs I frequent. I found out that it was a service (now) under Yahoo. As soon as I saw I already have an ID for it, I activated it and started adding services.
I added all services I could remember and then left it to that. Little did I know,it has a thing called "NewWithMe" which is a feed combined from the feeds of other services that were entered by me in the profile.
MyBlogLog being a Yahoo service, was updating my yahoo status message to the latest entry in "New With Me" feed every hour, even when I'm offline (i.e the state in which I am 95% of the time)
Finally, the mystery of the Twitter updates and "How is everyone who is not on twitter also talking about my tweets" is finally solved!
In retrospect.. it could have been very easy if someone clicked the blue line and saw that it redirected to MyBloglog :| Oh well, atleast I got to find out "everything" at Yahoo this way :P
Hope it answers all your questions!
