formatting inconsistency in single page post

I have noticed an inconsistency early on regarding how the single page posts display (default theme). The blog main page seems fine as far as I can tell, and I corrected earlier problems that you helped me with regarding copying and pasting from certain programs (all retyped directly into WordPress this time [www.waggleweight.com/blog]). For my initial four posts, when going to the single page format, three of the posts appear near the top of their respective pages with the other post titles directly above them. On the fourth however (A Golf Swing That is Mere Child’s Play), the post begins lower down on the page than the others, and I will add that the other post titles above that run together to such an extent that it does not look very professional. If you can offer any suggestions as to why this might be happening and a way to correct and avoid it in the future, I would be appreciative. Thank you very much.
