I've had this problem before.  I'm not exactly sure what causes it, but rarely I'll open a dataset in the design view and only the XML markup shows.  The first time this happened I made the mistake of running some Visual Studio reinstall command I found out there and lost a bunch of my personal settings.  Here's the quick, painless solution:

1. Close the dataset file. 
2. Find the file in the solution explorer, and click on the plus sign [+] to expand the subfiles of the .xsd file.
3. Delete the .Designer.cs or .Designer.vb subfile.  It will probably be the first of three subfiles.
4. Reopen the .xsd file to regenerate the .Designer.cs/.vb file thereby restoring your design view.

If that doesn't work you can always try a Visual Studio repair of some sort, but remember to backup your Visual Studio settings and any Code Snippets you've tweaked.

I'm not sure if there is a term for following someone on Twitter just to get them to click on your link but I'm suggesting the following:

Spamollow: (verb)

1. To follow someone on Twitter for the purpose of getting the user being followed to click on a link they would not otherwise in their worst moments of depravity or boredom click on.

Spamollower: (noun)

1. One who spamollows.
2. A parasite.

I've had jobs where on Friday afternoon I was already dreading Monday morning.  Not now; I love what I do.  I get paid to do what I would (and do) do for free.   Still, it's always a challenge to spool back up after vacation.
