I'm not sure if it is to be placed here of the editor/reviewers hangout. Over on the editor/reviewers hangout there is a thread with a few mentioning that they would NOT read a second sentence. I have found an area there I will not read the first sentence!
There seems to be a few grammar nazis on the site. The reviewers make notice when there are typos, wrong words etc. when doing their review. Your description of the story is the first impression that the reader gets, so it behooves you to make it an excellent one. Write it some time before you post and go over it several times looking for capitalization, misspellings, typos, and wrong words. Now I know it is very easy to see something that isn't there and not see what is there. Several years ago I worked on a hot metal printshop. We ran a special on business cards. I talked to a friend that was the manager of the local 4 lettered state university bookstore. Having a number of different colors, finishes and weights of paper that was not enough for 500, the boss made him a deal that if he would take the mismatched paper, he could have 3000 cards for the price of 2500. The lineotype operator made and checked the type. The boss put it into the form and checked it. I checked it and printed it, checking several times. The costumer received it checking the cards. Time went on and the costumer handed a card to a vendor. The vendor looked at the card and asked when they changed the name of the university. All that checking and handing out cards and NOBODY saw that the name of the state was left off!
