How can I tell? Because I'm getting a load of hits based on variations of two basic searches:
1) Capulet-Montague feud
2) Macbeth "Tomorrow and Tomorrow" Speech
I'm highly amused that my rather unconventional ideas for both of these are being used by dilligent students for term papers. What's great is how many countries I'm getting these hits from, and at what hours of the day. It's heartening to know that all over the world people are Googling the same question. No doubt they're reading Macbeth as a lead up to Halloween.
No doubt this post will only add to the hits. My advice to newcomers is to hit the tab for Essential Posts along the sidebar and scroll through them. Let me add, too, that I'd be delighted to field any additional Shakespeare questions. I won't do your homework for you kids, but I will try to answer your questions!
On an unrelated note, I got a strange little package from Lucasfilm today, from one of George Lucas's assistants. It was a copy of THE MASTER OF VERONA.
Which I wrote.
