If you find sparkles's comments helpful, great. I would not have found them worthwhile while I had high levels of typo problems (I've gotten better, but I'm not perfect - worse, my typos tend to change meanings rather than simply fail to make words).

Quality of writing improves with practice, but spelling mistakes of the kind you were making in the context you made them (comment section, via mobile device) are not closely correlated with quality.

If these mistakes really bother you, the lesson might simply be not to post through the Ipod, without getting into the emotional reaction that sparkles is trying to generate. Because whipsawing your emotions is not a friendly act.
