Word Count Wednesday--What Do You Think About Novellas?

I am so excited to post that I wrote 4652 words this week.  I nailed down a lot of my ending, but I still have a little ways to go.

The problem is, this book isn't exactly as long as my other books.  I've been mulling over a few ideas, like adding a secondary plot, adding a character, you know, the usual, but then I've also been thinking about making this a novella.

So today I have two questions for you.  First, what do you think about novellas?  Do you always want more, want it to be longer?  Or do you like them?

Second, how did you do on your word count this week?
