RiteTag is the only tool that helps you identify hashtags - for multiple social networks - based on words, not necessarily hashtag and schedule posts with thems. Interactive RiteTag Reports show content that has gone out recently with a suggested hashtag, influencers using the hashtag, how many times, and when the hashtag is used the most. From these hints, decide which hashtags to use, save them as a Tag Set or use with your content immediately.
With RiteTag, we curate content, aggregate, use the content discovered in RiteTag (with full attribution to original content sharer) where we wish.
RiteTaggers curate content into Collections, move content around, scrape from many social networks, and save it for reference or copy and paste - with proper, built-in attribution of the original content creator - for aggregation into a multi-author article.
Share content from Ritetag easily
Lastly, you can buff up the tags on other peoples' content and share content - directly to your own accounts in many social networks, directly from RiteTag.
Finally, I always like to take challenges: what topic-followers do you need to reach? Hit Saul Fleischman (me) up in Google+, and I'll gladly screenshare RiteTag, and show you what I would do to get your message to those not even following you.
