How to present mathematical expression in your blog posts

This is a critical problem,especially for those guys who are desired to write something on math or physics in blog posts.Currently there are mainly two alternatives:

1. Write down mathematical expressions in LaTeX and save the text as a ".tex" file.Run "tex2png.pl" or "textogif.pl"(a number of such scripts converting tex to images can be found on Web.Just google,you'll find a lot) to obtain a PNG or GIF which can be inserted to your posts.It is known to all that LaTeX are GOOD at processing math expressions,so don't worry about the quality of images generated.What bother me is that some blog systems,such as Blogger,behave strangely when I try to insert images to my posts.The server loves adding certain HTML codes to adjust the position,margin and so on to its preferences.I'm not familiar with these HTML and CSS tricks,so I never get what I want in Blogger.Finally I canceled this approach.
2. Write mathematical expressions using HTML's special entities.Hm,it does work,more or less,although they look somewhat ugly.Note:prepare yourself to suffer a lot from writing math formulas in HTML.If you decide to take this way,I strongly recommend Math in HTML(and CSS).The article offers everything you will care about in great detail.
3. I'm still waiting for someday when a more simple,elegant method for presenting maths in HTML pages appears and solves all problems.Blogger wolverinex02 implements a LaTeX compiler for blogger,see his page LaTeX for Blogger.The idea seems excellent,but the implementation now still needs some improvements.
