I know I have a low karma. Is this of high importance when trying to get to the frontpage?

"I know I have a low karma. Is this of high importance when trying to get to the frontpage?"
As far as I know, karma doesn't factor into the algorithm that decides if an article gets to the front page. There are occasionally articles from newly created accounts on the front page. However, if you're a well-known user with a reputation for posting good stuff, people might be more likely to click on your article.
If you're a new user, you might want to look at the Guidelines and FAQ links at the bottom of the page.
