We now have Blue Sky, written by the guys who wrote Twitter; there is no icon for this, but there will be new platforms coming along, and how do you keep up? Therefore, to be able to customize your social share would be useful. Then define your CSS name as 'sshShareOnxxxxx01', with the custom behaviours as a template, is this page as a template token '{url}' , this also needs to deal with "Comment on the page" (not just share it), to copy the URL (to cut and paste into a SMS message or WhatsApp).    This social share is part of the new world, eg what do you do with a share with voice.
Eg attach this URL to a WhatsApp voice message? 
This would be useful in Campaigning when you want to send a URL and a voice message (e.g., "Vote for Me").
You also need to have in the template a localization flag. We can assume its always en_us but that's not Telerik,
Also adding the CSS content as a SVG would be good to.
Also would be nice to have this in KendoUI as well.

Hello,

 

In the social share there is no option for Instagram.

Is there a workaround?

There are a number of useful parameters to Twitter's Tweet button that it'd be great to set using the RadSocialShare interface, notably the "via" parameter, which tacks on a related Twitter account to the end of a tweet, as in: "Check out this great site! http://www.url.com/ via @GreatSites", and the "hashtags" parameter, which tacks on hashtags. Available properties are listed here: https://dev.twitter.com/docs/tweet-button#properties.

The print button will be part of the styled buttons collection, similar to the MailTo and SendEmail buttons.
