I just noticed that entries got mixed up in the feed. This happened because last night I had noticed that formatting of the first paragraph in all of my posts had not been proper and changed it. I did not know that it would have any effect on the posts in the feed. Since I had not change any of the dates, I will go through all of the entries once again in order to straighten their order in the feed so that chronology is preserved.
Sorry for any inconveniences
