so if you leave the page open, you always see the latest trends

Lets have a look back to past trends, this could be interesting for research and for regularly returning trends (i.e. christmas)

In addition to Sports, Technology, etc. you should have an option to choose Conference because so many hashtags are being used for discussion of conferences (like TC50, #140conf, etc.). Some are technology conference but others are more social media or on other subjects where none of your tags fits.

You also might consider adding TweetChat or Webinar for hashtags used for live conversations on Twitter and an option to "untag" a TT that has been tagged inaccurately. Once an option is chosen, the editor can only choose another tag and sometimes none of the choices fits.

The general description could be auto-snagged from Wikipedia or user-added - e.g. the information a person is a singer or television presenter, or the expansion of the acronym naming an event - and then a second section could explain why it is trending today - e.g. they just appeared on a certain show, or someone notable just spoke at the event.

Specifically, the weird #eggplant topic has been trending all morning (and probably last night). Its definition shows it to be an active topic but it's not listed in your top 10 or on the front page at all. Your list should really be in sync with Twitter's list, no matter how ludicrous the topic unless Twitter yanks the topic off its List.

the problem with weird trending topics is that you don't know why they started trending. it would be cool to be able to see who the first people to tweet about it would be, and follow how it grew. as it is now, you would have to scroll all the way through every tweet until the very beginning.

i find it weird that "politics" is missing as a category.

just like on any forum-type news sites people would discuss each topic/newsbit and share their opinions

E.g. I could tweet @whatthetrend 3764 <the trend> is because...

3764 being the trend id. <the trend> would have to include the trend text. Then you could do a simple cross check of id and trend before posting in order to stop spam.
Then list tweeters and their suggestions on the web page. People can click to RT a suggestion or to contact the tweeter.

Try to create search algorithms to identify closely related articles and tweets (For example: The topic "Conan" is tweeted because of the videogame "Age of Conan" as well as because of late night talker "Conan O´Brien"). Identifying these different reasons for one trending keyword automatically would be nice.

Blocking spam bots in twitter is a better way for people to fight spam, tip off twitter about spammers, and clear up clutter in their stream. If more people block spammers, eventually the metric of being blocked by large numbers of people will help filter for 'real' trends

... or, create an RSS feed option that filters out the jokes and NSFW stuff. I find the What the Trend feed super-useful for news, but the NSFW factor almost ruins it.

Let us get trend data that is days if not weeks old...

For some reason, my edits in the Beta version appear in the history of the Topic but the Topic itself isn't altered, it's an older version. This is seconds after I've made the edit so it's not like someone reversed the edit. Also, I haven't hit my edit "limit", it was only the 3rd edit I made. I've worked in the Beta version before with no problem.

Allow incorrect definitions to be altered. My band's acroynym is trending with the wrong description
