News aggregators take selected Twitter accounts and include them with the rest of the news on major equities or commodities. Most often these accounts simply echo the other news sources, they're not giving you the rich insight offered by a wider range of Twitter users that you control. EarlyBird users typically follow a number of Twitter accounts that they trust, together with SmartTracks to bring in further financially relevant Tweets from other Twitter sources you wouldn't have thought of.
In a recent side-by-side test over a 20 minute period, we found a major news aggregator ignored more than 30 Tweets on a particular stock, several of them with market moving content, which EarlyBird included. With EarlyBird you can adjust the curation so you get rid of the noise most of the time, then open the filters up when you want to delve in further, say to investigate a price move the aggregators can't explain.
Yes. EarlyBird is used on some of the largest tradefloors in the world, fully locked down. We have never required any IT group to make any changes to their network, firewalls or desktop configuration, and users do not require admin rights to run the main web client.
Premium users get access to The Warbler - a tasktray app that gives you Tweet popups on your choice of screen or location, with your chosen filtering. This needs admin rights to install, but again no changes to network or firewalls etc.
