Explore the Speaker Database to find a speaker whose biography mentions 'data' or 'analytics' and identify their name, their primary role or expertise, and their Twitter handle if available. Do not use the search bar for this task; instead, browse the list.
Navigate to 'personaldemocracy.com'. Click on the 'Speaker Database' link (id: 146). Scroll through the alphabetical list of speakers. Examine each speaker's biography for keywords such as 'data' or 'analytics'. Once a speaker matching the criteria is found, extract their name, primary role/expertise, and Twitter handle.
Identify at least one speaker whose biography contains 'data' or 'analytics'. State the name of the identified speaker. Provide the primary role or expertise of the identified speaker as described in their biography. Provide the Twitter handle for the identified speaker if listed. Confirm that the search bar was not used to find the speaker.
