Broken Twitter avatars, verbose Twitter links

In Firefox using "Strict" for my privacy mode, Twitter avatars are missing (this image is from the home page):

Thrilled that there is alt text, but the missing images also highlight that the links are duplicated. This adds unnecessary tab-stops and redundancy, not to mention it might make users think the different links go to different places. I suggest removing the links from the avatars and giving them `alt=""`.

As I tab through the page in NVDA, I get this (`Tab` is me pressing the Tab key):

> Lea Verou link
> `Tab`
> Lea Verou link heading level 4
> `Tab`
> Nicole Sullivan visited link
> `Tab`
> Nicole Sullivan visited link heading level 4
> `Tab`
> Philip Jägenstedt link
> `Tab`
> Philip Jägenstedt link heading level 4
> `Tab`
> Christopher Kirk-Nielsen link
> `Tab`
> Christopher Kirk-Nielsen link heading level 4

If I just let the page read through, from the "Special Thanks" heading I get:

> Special Thanks heading level 3
> link Lea Verou
> heading level 4 link Lea Verou
> Survey Design
> visited link Nicole Sullivan
> heading level 4 visited link Nicole Sullivan
> Survey Design
> link Philip Jägenstedt
> heading level 4 link Philip Jägenstedt
> Survey Design
> link Christopher Kirk-Nielsen
> heading level 4 link Christopher Kirk-Nielsen
> Logo Design

Related, I do not think those links need to _also_ be a heading (at any level).
