While tweeting I noticed that even though I have marked the tweets with "#in" tag to selectively push it to LinkedIn, but it doesn't go through. So I thought let me download the "hootsuite" app for Mac OS. On the download page I noticed that there is something called Fluid, which lets you run the web app as an independent desktop application. I liked this idea.
Next thing I did was download the app and tried and creating an app for Hootsuite itself, it worked fine. You might want to download the icon of the app you are trying to mimic. It's simple, very straight forward and easy to use.
By the way, I noticed this app "Fluid" because the "Download Now" link on Hootsuite webpage showed me 404 (due to my intermittent network problem; Thank you Airtel for such a wonderful timing !).
