This is my opinion. Not trying to lay down any absolutes. I have not even fully formed this train of thought, just a gut feeling.
Design learning is about listening to superiors, professional educators, and working with, and in competition with, your peers. It is about working with materials and ideas and developing your talents. The hours that count are the ones you spend in the studio and in reviews. The face to face interaction with people that give you praise and people that give you criticism.
Going global with assorted web venues during this period seems to me to put the serious risk wrong emphasis on your work. Instead of the freedom to experiment and fail, you become more concerned with pleasing your “audience”. You become safe and slick, or you aim for that. You might compare yourself to the best sketch stylers in the world, instead of realizing that the ideas are what matter most, and developing a repertoire of skills.
The voices that participate in online discussions are much harder to evaluate. Experience, ability, area of concentration are all often vague or a complete mystery. People often give strong opinions about things that they don’t have the experience or depth to back up. Like many areas on the internet, there is a low or indeterminable signal to noise ratio.
I think in this forum, as in many, the positive is accentuated. As responders, we generally want to lift everyone up, we are also aware that we are playing globally, and don’t want to come across as harsh or negative. I remember some hard critiques in university, ones that can be delivered personally, or in a small group, but not in front of a hundred or a thousand people. Here, the choice is usually to remain silent when a harder critique is needed. With all of the positive voices, you run the risk of believing your own bulls__hit. My gut tells me that during the period of development, the more your ego is in check, the more open you are to becoming better. My impression is that the peers around you are the key.
Build a web portfolio and keep it updated as your work gets naturally better, participate in discussions. For your work, try first to get feedback from your local peers and professors. If that is not sufficient, then be sure of the reasons that you feel it necessary to look to a wider audience.
What matters most is your final selected work, that is really the stuff that you want to share with the world and your future employers.
