It hasn't affected me in the slightest, other than making me hopeful that some of the more obvious dreck will be weeded out before it can be indexed. A site full of poorly written, error filled garbage that exists only to try to push readers to someone's commercial site reflects badly on the writers that *are* trying to write well or share information that they've got some degree of passion about.
Unless you're writing current - breaking - news, a wait for indexing isn't going to be a problem. And to be honest, if you want to write news, Hubpages has never really been the best venue for you; there are thousands of sites out there that specialize in that (and thousands of people trying to hop on the latest hot story - and to be honest, very few of the people writing 'news' are doing anything other than repackaging someone else's reporting).
Everyone's publishing schedule is different, but there's no reason to delay publishing a finished article based on when google starts searching, because it doesn't really start searching - it crawls 24/7, and there's no way for anyone to know when its little bots are going to hit next. You may as well publish - sure, an article may be pending for 24 hours or so, but it's still going to be 'live' before an article that's never been published.
