I am in process of uploading a paper for arXiv. I have looked over the paper for several weeks now and it seems that there are no major issues, however, the paper is 24 pages long so I have accepted the possibility of having a few (non-trivial) typos and grammar mistakes here and there.
My question is, what should you consider before uploading a revision to your already uploaded paper, should you spot a mistake?
I am only asking because it seems that the people I have came across in my field rarely upload a revision, whether or not there are mistakes in their paper. One, for example, contained a glaring mistake in an important part of a proof, but the mistake is still there; I can see it now. The paper has been there for a year now, it has gone through a formal revision at a conference (where the mistake was corrected). But why not simply correct their arXiv copy?
Should I wait until more feedback is received before uploading a new revision? If so, how long? Is it okay to upload the revised version immediately or is there some arXiv mechanism that prevents me from doing so?
Is there a catch for uploading revisions?
