Firstly you have not properly created the internal like of the site in this Forum thread. You have put the URL in the keyword of the link. That is wrong, by that no one can open your link which you have mentioned. But as I have some knowledge regarding the links I have successfully opened the link which you wants to mention. The link is: http://www.techulator.com/experts/4210-How-to-get-viral-on-Social-Media.aspx, simply this. If you want to create such internal link then you should not use the link itself at the clickable place. You can use the question line or another keyword which better describe the thread. This is somehow also related to SEO.
Now coming to the thread, there is no reason of worries my friend. Your answer might have been left by the Ask Expert section editors while reviewing other answers in that thread. Or they have not reviewed the answers from a long time. There can be any reason which is not known by me. So all you need to do now is just wait for sometime and by the link I mentioned in my response the editors will get to your answers and will review it as soon as possible.
I find that the harder I work, the more luck I seem to have.
