Thank you everyone for all the constructive criticisms and advice. That is exactly what I was looking for, both the criticisms and advice.
Sorry I was not able to direct reply to each comments. I think I should have asked the question when logged in instead. Too late!
Anyways, many of you suggest that I take the advertisements down...there were not many ads on the site until just a couple of days back. Since the traffic was not huge (I get moderate traffic though) I thought of trying ads anyway. But it surely looks like that's a turn off and I'll try to minimize that impact. Just for your information the site has been live for more than 1 year now without much advertisements!
Once in a while I see performance issues with the host but then it goes off pretty quick and the site loads at a decent pace. I've been using most of the performance boosters to make sure the site loads quick. May be, as many of you have pointed out, because of too much content-clutter on the page you are noticing the performance penalty I guess.
I would certainly take all your advices and would start working on to improve the time my readers stay at the site and also to make it easy to find the information. May be it's time for a UI revamp! There is another side to this that I get many emails in favor of the layout that I have and that's the reason I thought it's working out okay. But, as you've pointed out, reducing the clutter is always a good idea and it would help with the page load I would certainly take your advice and would tweak it in that favor.
I would also focus on breaking the post into smaller digestable chunks. The nature of explaining how to do things in tech makes it to go longer and longer. Of course, if I can work on to reduce the length of the posts that would reduce the stress on my wrists as well!
Any advice on how to market my content the effective way. I've been doing it on Twitter and StumbleUpon but that seems to be not enough to "take off" as I've mentioned before. It does receive decent traffic from those social media outlets but I keep going back in comparing it with my competing sites and there's a big difference in terms of traffic numbers. I'm sure I'm missing some of those recipes and I would like to take your advice on what those recipes would be and how to use it effectively.
Once again, thanks for all your detailed responses, Harv, JM, Centurion Games, Claus Schwarm, Ben MC, Bob Walsh.
Bob - that toolbar is called "Wibiya" and is in beta testing I guess. Mashable and many others use it and I thought of using it for the direct communication popup.
