it helps me stay organized and productive.

What differentiates Slack from other similar products?
it’s superior to just about any old consumer chat app because it’s designed with professional etiquette and features. for instance, the option to limit who can post in which channel is a requirement for say announcement-only news. its businesses features, such as single sign-on (sso), are critical for larger & more security-conscious enterprises which simple solutions lack.
What is your favorite aspect of this product?
i like the flexibility of custom notification sounds and how easy it is to switch my status to show i’m on a call or out, etc. file preview is awesome; i can see pdfs, document inside the chat and read without downloading them. lately i've been doing polls with a slash command from the backlog of hell to get some quick team decisions. being able to search all files shared in all channels is a huge organizational plus.
What do you dislike most about this product?
i still think the video call quality in slack is a little hit-and-miss compared to dedicated video conferencing apps, especially on a slower connection. it would be good to have also better options for formatting messages here, e.g. simple tables.
What recommendations would you give to someone considering this product?
i cannot recommend slack highly enough as the top communication tool for today\u2019s moving, fast-paced teams who require that their projects and/or conversations be extremely organized, easy to search.
Pros
- Continually Improving Product
