Trying to jump into the technical world of social media

Goodness, do I ever feel lost....seriously thinking about taking a computer class in windows apps - if there is a class. Every hour it seems as if there is something new and available to try and apply. When I am looking at them it is ohh I want to do that it is only $10 a month and then oh I really have to do that and look it is only $15 a month and look here this is only $89 a year ...well I think you get my point at the end of the month they all start to add up - which one is best?
You know you want to get aboard with Craigslist, facebook, linkin,activerain, twitter and youtube and the list goes on and on...........this is and can be so overwhelming and I know I can't be the only one...maybe a club can be formed for the lost and confused assuming I am not the only person out there who is struggling to find there way thru all the latest greatest new products that are available out there. Thankly, my office has a wonderful man by the name of Rick Tankersly who is trying very hard to lead me into the scary technical world of smart phones, Ipads, and social media. If there is any other person out there who is just as baffled I urge you to take it slow and find someone who is willing to patiently walk you thru all of this. My guru's advice tackle a couple of items get confident with them then start on another one it will all start to pull together.....Wish all of you at there lots of luck if you are in my position to those who have it all together Kudo's to you one day I hope to join your ranks!
