Don't hit your head on the wall to name a weblog. Choosing a random name is fine, however, I wouldn't recommend pneumonoultramicroscopicsilicovolcanoconiosis for a name. Choose an easy to remember name even if it doesn't make any sense. Content is everything Content is everything.
Great contents make great weblogs.
Be original be unique. Always comment on links you provide. Tell the readers what to expect and what you think about it. Be observant, that is one of the best ways to find great contents. You are unique just like everyone else.
