Look at the question [How do we maintain answer quality when everybody thinks they're experts?](http://communitybuilding.stackexchange.com/questions/1113/how-do-we-maintain-answer-quality-when-everybody-thinks-theyre-experts).

If I hit Ctrl-D in FireFox this is what it proposes as link text:

<blockquote>
content curation - How do we maintain answer quality when everybody thinks they're experts? - Community Building Stack Exchange
</blockquote>

It's obvious that the (first) **content-curation** tag is prepended to the link text (sanitized to remove the hyphen).

Now look at [Advantages to storing content locally vs outsourcing it to a 3rd party](http://communitybuilding.stackexchange.com/questions/667/advantages-to-storing-content-locally-vs-outsourcing-it-to-a-3rd-party).<br />
If I again hit Ctrl-D, this is the proposed link text:

<blockquote>
small communities - Advantages to storing content locally vs outsourcing it to a 3rd party - Community Building Stack Exchange
</blockquote>

The text of the **second** tag is prepended.

If you look at the [edit history of the first question](http://communitybuilding.stackexchange.com/posts/1113/revisions) you see that the tags were never edited. The second question currently has no edit history.

**Question: what determines which tag text gets prepended to the proposed hyperlink text?**

I have searched [here](http://meta.communitybuilding.stackexchange.com/search?q=is%3Aq+bookmark+tag) and on [meta.stackexchange.com](http://meta.stackexchange.com/search?q=is%3Aq+bookmark+tag) thinking that this question actually belongs over there, but with no results. Actually, this prepending of tags does not happen across SE sites (tested on [SO](http://stackoverflow.com/) and on meta.SE itself) - for all I know it could be specific to Community Building.
