Criticism on hubpages - Take it or leave it
Being overly critical isn't wise
Response to a Q&A
The leaving of insightful comments is what I'm looking for from my viewers, and is the very reason why I even create a single hub, I care not for their scrutiny, I care not for the spelling or as you've stated poor grammar.
I look for reactions and responses to spark a great informative feedback mechanism using the comment section. If my hub scores many comments, It feels like a reward to me for doing a great job, and no matter if its positive feedback, negative or neutral. As long as I now have a sense of true interaction, I simply begin to feel awesome for some reason, and as if my initial mission is accomplished.
To me hubpages is a great system for constructive criticism, but many people have no clue as to do so, or even fully comprehend what it is to be original, insightful, or even have a position on things in life by using their words to support such a stance. This is probably why when you see a comment that has very little supporting structure, it may appear to be of weak foundation.
Leaving Insightful Feedback & Sincerely Meaning It
Feedback is powerful when done with true integrity, and with that stated I make sure to leave people great feedback on their hubs, or if not, I would actually feel as if I may have cheated them out of doing my part as a reader who cares for their efforts. Accountability is another huge factor when it comes to commenting, so if someone just stated something open ended, be mindful that there may be an opportunity for someone to call that person out on it.
Even if it wasn't addressed to the person who responded to such a pointless comment. Hubs that have controversial topics, will tend to draw the most comments, and if your going to join in on any conversation there, you better expect to also get drawn into a heated debate, or discussion between others from all view points.
Exploring Everything in Life
I'm not sure if this is a question or if it was a lecture of some sort. Just because someone hasn't corrected errors in a comment, doesn't mean they're having troubles with their English.
I personally have made many typo errors, and have no problems with English, its more of a keyboard error for me. Being to judgmental is a huge issue here on hubpages, and in life in general.
Don't be so quick to judge others behaviors though, & surely not behind a computer screen, because we don't know every ones situation and or circumstances their currently in. In terms of making it here on hubpages, or as you've stated in this market may actually be purely a random occurrence, because if your truly nice to people, funny, zany, or exciting person, it might make all the difference, & may not matter the way you spell to much or present your info, those same people might just return the awesome gesture.
People might just love your efforts to draw & attract others attention as well as entertain them via hub writing & providing great content, I've seen and read from authors who are all from differing countries, and are very successful on hubpages, plus their English isn't to good in terms of their writing, and commenting.
For those with issues with their English as a second language, no one seems to think there's a problem judging by the great feedback they all receive daily, and also due to the fact of English not being their first language. I don't see a problem with how they communicate neither, its the best they can do, and many of them are learning from us simply by reading our hubs. That was a respectable question, but I don't see its true purpose though.
