Following Yahoo Messenger's shutdown on July 17th, the company primarily known for its search engine has been testing a successor, known until now as Yahoo Squirrel.
As covered back in June, Yahoo Squirrel, officially billed as Small Yahoo! Messenger iconYahoo! Messenger's successor, was more centered on group conversations instead of Messenger's more one-on-one dynamic. Now that it is known as Small Yahoo Together iconYahoo Together, this has not changed. Yahoo Together is more similar to Small Discord iconDiscord than it is to Yahoo Messenger in how it approaches conversation management.
As Mariella Moon at Engadget notes, Yahoo Together has a few features that are worth noting. This includes a searchable shared file library in each group conversation, enabling people that utilize Yahoo Together for collaboration or productivity to easily access files previously uploaded. Of course, at that point, collaboration software such as Small Slack iconSlack may be more appropriate. There is also "smart alert" functionality that parses dates and times in messages and allows users to click on them in order to set a reminder that will notify the user when that time comes to pass.
Again, as noted back in June, messaging services like Yahoo Messenger that are less focused on group conversations include Small Signal iconSignal, Small Telegram iconTelegram, and Small WhatsApp Messenger iconWhatsApp Messenger.
