Vine, Twitter's new video-sharing service, is currently all the rage. The iOS application lets users easily capture and share short looping videos, which has led some to call it "Instagram For Video." Here are six things you should know about the app.
1) Flooded With Porn
As it is with any fast-growing social media application, Vine has a porn problem. A search for hashtags "#porn" and "#nsfw" will produce hundreds of six-second clips that aren't for the faint of heart.
Vine warns potential viewers when a "post may contain sensitive content" and asks users to tap to view possibly risque material. Early Monday, a porn video shared by user "nsfwvine" received the service's "Editor's Pick" badge . A Twitter spokesperson told NBC News in an email that a "human error" was behind the choice and the badge was removed immediately after the company noticed it.

2) Facebook Dislikes It
Facebook has blocked the new video-sharing app from being able to find user's Facebook friends on the new service.
In a post explaining the move, Facebook wrote that it has policies against apps that "bootstrap their growth in a way that creates little value for people on Facebook."
Last Friday CNBC questioned whether Vine will push Facebook to add a video feature to any of its mobile applications. Late Monday, it did. The company's updated iOS application now lets users record and share videos, as well as voice messages.

3) Early Hiccups
Early versions of the application are buggy. A Twitter search for "Vine failed" on Sunday produced dozens of angry tweets.
Users were complaining of "failed uploads" after spending minutes at a time working on a single Vine clip.
"After 5 separate failed attempts of uploading a Vine video I don't think the app is anything other than frustrating," tweeted Ian Coles.

Twitter Design Manager Martin Ringlein attempted to encapsulate 3,000 miles into six seconds of video and failed twice. One successful try was labeled, "World's Longest Vine."
4) Claim Your Name
Similar to Facebook, Vine has an issue regarding duplicate usernames. Since Vine's system currently identifies each user by a number on the back-end, two users can technically be "Barack Obama" on the front-end. To solve this issue, Vine is now adding verified badges for high-profile users.
Whether or not you want to start Vine'ing today, we recommend you at least claim a text-only username on the front-end. If the app decides to hand out vanity URLs based on the name a user chose, you'll be in a good position to have your preferred username.
5) Developers Getting Creative
Developers are already doing some fun things with Vine posts. A site called Just Vined features 20 of the most recent clips published on the platform. Vinepeek, another tool, will show you the world's newest Vine in realtime. "Sit back and watch the world in 6 second bites," Vinepeek exclaims. "This stream… is [not moderated]," it warns.
6) Business Applications
Businesses are already using it to fill jobs and give house tours.
Jeff Weiner, CEO of social media rival LinkedIn, gave the app his approval tweeting, "Looks like @Twitter is on to something w/ @vineapp."
Ritz, Dove and Trident Gum are getting in on the action, too. Whether a brand can tell a story effectively in six seconds will be interesting to watch.
