Punctuation - How important is it online?

YES! I hate poor grammar and I cannot stand to read things that are very poorly punctuated. The odd tiny technical mistake is fine, of course. Once it affects the reader's ability to understand, then I think the author loses readership, potential friends who would read and comment, and respect.

It isn't that important. Just make sure what you are saying can be understood. I mean sometimes a period can really make a difference in a sentence you see how I didn't put a period after the word "sentence" just now? That could really confuse some people on what I am saying. You don't have to go on a comma frenzy or something like that, just make sure we can understand what you are saying. That's all that really matters.

sure.It is needed in mylot.Because if you want to express your feeling and if should be understandable to who read the message,i hope punctuation is important.

i generally punctuate but i rarely capitalize. is that ironic?
