Slack has been a platform for us to connect share and work together It's broad features like files sharing, integrating with Web hooks, finding workspaces, individual chats becoming more focused even in group, following # concerned to your topics and more I can just go on differentiates it from others
What is your favorite aspect of this product?
Able to search across workspaces Make and implement bots, Follow activity Communicate in groups yet individually via DM The way one chat becomes a full screen chat in next window makes it focused on just the thread is amazing
What do you dislike most about this product?
It's most cluttered platform Asks for multiple verifications for login Cannot keep a track of your own messages in group when audiences are more Most of them use for support function that makes it even worse Searching across platform for another workspace outside which I want to join directly it's truly devastating despite that being a public group
What recommendations would you give to someone considering this product?
Make the ui clean uncluttered Make few functionality where in a group I can track my messages and it's replies on thread Make logins easier without multiple or triple verification Make workspaces which are public searchable other websites are making a list and sharing on their website which is not trustworthy and thus it affects even good ones
