Thanks. I'm not sure if I understand it correctly. I just couldn't find a
robust information from the article to proof that <ol> is no more and no
less ordered than <ul>.

Throughout the article, I saw it mentioned "bullets" and "numbers"
frequently. However, that's just browsers' default rendering of <ul> and
<ol>. As a coder, personally I don't care how browsers render them by
default. What I care is the meaning of the code I write. That is, when I
want an unordered list, I write <ul>; when I want an ordered list, I write
<ol>. <ul> means unordered list, and <ol> means ordered list. It's that

Although there may be some people misuse them (like the example mentioned
in the article), that's not <ul> and <ol>'s problem.

If I missed anything, please let me know. Thanks again.
