Could you please elaborate on your thoughts regarding the quality of bubble websites? I'm quite curious to know your perspective on whether they are considered good or not. Do they offer valuable services and features that justify their existence? Or do you believe they might just be a passing trend with limited practical use? Could you share some examples of bubble websites that you find particularly noteworthy, either positively or negatively? Additionally, how do you assess their potential for long-term sustainability and growth? Thank you for your insights!
