Going to classes, the online way

Recently, there have been a lot of announcements regarding free online classrooms for instructor-led E-learning. I was a bit skeptical of it at first, but now am glad that I enrolled myself into it.

Some of the advantages that online courses offer over conventional courses:

• All the comforts of an online\distance learning course for free.
• Vibrant discussion forums that help erase doubts.
• High quality material: These courses are taught as-is in the real classes in top universities.
• Hands-on learning: The learner gets to create programs and solve practical problems related with the topic.
• Stay focused on a specific topic - working as a professional developer, it is natural to get stuck with the mundane aspects of programming and forget the big picture as there is the excitement into hacking into different topics without much time constraints, like in college. 

I am currently enrolled in two courses at coursera.org and one at edx.
My first course is a 10 week course about Big Data, which I had an inking that it would be related with hadoop and other high level aspects of it, but what surprised me was that the first three weeks of this course have passed and the instructor is tirelessly helping us understand the basics/theory of the importance of big data and its key challenges. This being an IIT post graduate level course, further lends credibility to its undivided concentration over the background aspects of  big data (and intelligently breaking it down to look, listen, learn, connect, predict, correct).
Another course that has just started is Programming in Scala by none other than its inventor itself, Martin Odensky. What is pleasant about the course is that right from day one, the course uses test driven development and sbt for building & submitting programming excercises.
I also have high hopes for the upcoming SAAS course offered by MIT that seems promising and offers me to create a cloud based solution after a long time.

These myriad courses do take up time, especially the after work hours, but is a better use to put my time rather than just browsing around. So, lot of efforts and headaches are induced into this process, but is worth a try - whether you are a student, a developer or a curious bystander who happens to have some of these type of subjects affecting them in one way or another.

Are we a dying breed ?

Is it really beneficial to build and maintain an online persona when it is fraught with problems all around the corner? This thought was echoed on a thread on javaranch.com, which happens to be a very popular social forum for java technology enthusiasts.
One of my acquaintance had also, quite recently expressed reservations about the same due to the lack of appreciation. Whether his comment is just his perception or is it the truth, remains to be seen. The concept of professional blogging too remains an elusive concept for me and as far as I have observed, this remains largely and exercise in isolation or through and 'tool'.

In the google trends on blogging, it appeared that the search volume index dropped to an all time low in the last quarter of 2010 ever since the usage curve became consistent since 2007. The reference of blogs in the news also became erratic and dropped during this period.

This leads to an interesting conclusion; is twitter really ushering in an era of microblogging since the people don't really want to go that extra mile for sharing their thoughts ? Applying social networking in the above comparison definitely causes no raised eyebrows as it is quite clear that social networking has taken the lead for the online citizens.

As the aftermath of this change, you can expect greater emphasis on the management of information over these platforms - both for commercial and research purposes as well as a general change in the dissemination of information. This is because instead if the traditional Author-reader/follower role, we're fundamentally shifting towards an peer to peer approach with spontaneous interactions. So instead of following your favorite blog and waiting for the posts to come in, real time and probably, geographically aware interactions rule the roost. Social networking today has spread much beyond socializing with friends, family and that 'hot chick' profile(pun intended) to an information sharing portal. It is customizable as a mini internet with all the users being able to be the generators of the content.

So if you are a techie or business savvy, you can utilize this change for your benefit. What do you feel about this ? are there any new developments in this arena that you are aware of ? please do comment about it.
