of course you do! - time to get making hd video content for vine!
having a channel with regular hd content, using the 'watch more' feature is a good way to be present on this platform, remember that both instagram and vine have the ability to be searched using hashtags and titles.
having cinemagraph content for instance posted regular can drive attention to your website, just make sure your newsletter signup is of value when they get there. maybe you can offer a training course on how to make a good cinemagraph. your process and tools you use in a super fast screencast work best.
i've managed to get freelance work based on my cinemagraphs and work on wirecast. you never know where your next customer will come from so why not be everywhere you can! :)
also, check out this vine channel i made as an example. .
i made some videos with audio soundtracks, clicking on the remix button will allow me to make a vine on my other account using this audio. this is a good way of taking your audio content library with you on the web. have a think how you can use this technique for the output you are working on!
