Yes, you can tweet from Google Glass

LeWeb founder Loic Le Meur confirms to CNET that he's been using a third-party tool called GlassTweet to tweet photos.Due to erroneous information provided by a source, the original version of this report misidentified the app as an official Twitter app for Google Glass. It is in fact an app produced by a third party.

There's no doubt about it: Google Glass is already being used to send tweets.
For now, however, it's not known for certain that anyone has done so with an official Twitter app for Google's wearable computer. What is known is that LeWeb founder Loic Le Meur has been testing out a third-party app called GlassTweet that offers users a rudimentary way to tweet photos but little else.
This afternoon, Le Meur tweeted a photograph taken in San Francisco using the hashtag "#throughglass."
Le Meur said that GlassTweet is "very simple, and it's very limited. Basically, you take a picture. You take it with your voice, which is cool, especially when you're driving."
He added that the app offers multiple ways to share a photo. First is Google+, which makes sense given Glass' provenance. Twitter is second.
Though GlassTweet is a third-party app, there's still reason to believe that Twitter has an official app in the works.
TechCrunch reported Monday on the likely appearance of tweets being posted in the wild from what seemed like a Twitter-created app for Glass. But Twitter wouldn't comment about it, and the tweet that spurred the report was quickly removed.
In its article, TechCrunch pointed out recent comments made by A-list venture capitalist John Doerr, who was heard to have dropped hints at a meeting of the Glass Collective that Twitter would likely soon put out an app for Glass.
What Le Meur's tweet showed is that Glass is ideal for tweeting photographs. But the question about such a device -- and Twitter apps, whether official or third-party, for it -- is whether it would be useful for more text-oriented purposes.
That's the obvious challenge for Twitter, and others jumping on Glass. Can they adapt to the device's voice and tap interface? Taking a picture with Glass and tweeting it is a relatively simple function of setting the Twitter app up for the device. Twitter, however, has traditionally been a text input service, used with a keyboard, even if that keyboard is usually on a mobile device.
Now Twitter service is starting to branch out, and Glass could well present its users with new use cases, such as video "tweets" from Vine and audio tweets with a limited time span, a kind of parallel to the 140-character limit. Presumably, Glass could enable users to dictate tweets to Glass, but voice recognition has clear limitations, and plenty of inaccuracy. So it remains to be seen how such applications will play out on the device, and on other similar wearable computing equipment that is sure to come along.
