Can Google+ build on it's 25 million first-month visitors?

Google+ managed to attract over 25 million visitors since it opened its digital doors on 24th June, according to research from Comscore. Thtis is much quicker than the early growth of Facebook, but Andrew Lipsman, ComScore's vice president for industry analysis, told the LA Times that speedy uptake does not necessarily mean stable and sustained growth. He said that Facebook's growth was much more steady and stable than that projected for Google+.

Here at BD, we've been checking Google+ out and although the 'Circles' functionality certainly improves on the Facebook privacy settings, it seems that this is the only major improvement over Facebook. Otherwise the layout is strikingly similar, aside from slight cosmetic changes, such as being able to use italics in status updates. We've also noticed that they may be a severe flaw in Google+ in terms of spamming. It is currently possible to import up to approx 5,000 email addresses, click "select all", drag them into a circle and start spam messaging. This is similar to how spamming works on Twitter, but in this case the spammer can have thousands of contacts from the get-go. You cannot do this currently on Facebook, and Google may have some sort of impenetrable spam filter in the offing, but it doesn't seem to be operating now.
